today i'm going to show you some awesome dry ice experiment for this first experiment
you're going to need some pure alcohol some dry ice a large bowl and a glass container
pour the dry ice into the bowl and then add the alcohol
i've used three small bottles of it for this experiment
you'll see that mixing it with the dry ice causes a reaction it will bubble away however
you don't get quite the same reaction as when you add water the extreme cold
temperature of the dry ice will instead reduce the temperature of the alcohol to below freezing
using this method we can make homemade liquid nitrogen
which will freeze anything we put inside it how awesome is that
let's add a little more dry ice
now let's put this marshmallow inside i'm going to dip it inside for about 10 seconds
now let's take it out and you can see it's almost rock solid it's difficult to cut it
with a knife now let's try this jaffa cake i'll dip it for another 10 seconds
now let me just try and bend it in half
and look at that it snaps it's gone extremely brittle now let's try something like this balloon
once we take it out well look at that
the rubber has frozen in shape the extreme cold of our liquid nitrogen has that power
this is a really cool experiment now let me show you the dry ice snake skin for this you're going
to need a small tube a large plastic tube some dry ice washing up liquid food dye and a large
jug of water first take a few drops of your food coloring and squeeze them into your small tube.
then pour the water inside until the tube is almost half full
add a good measure of your washing up liquid to thicken the
solution mix it up by hand then fetch your glove and drop in a few beads of the dry ice
very quickly you'll get a great reaction look at those bubbles go bubble is filled with
the mist created by the dry ice so when they burst you get little puffs of mist
look at it go now let's try with a bigger tube repeat the process but use slightly
more ingredients than you did last time this time we'll use a good measure of the food dye
a large amount of the washing up liquid which will mix together
roughly a pint of water
and a handful of the dry ice pellets and look at that reaction so many bubbles each filled
with the mist from the dry ice reaction this is a slightly messy experiment so you're going to
need some kitchen paper or some towels to catch any of the excess but look at it go
for this next experiment i'm going to show you dry ice gummies you'll need some dry
ice some pure alcohol a pair of pliers some gummy worms a hammer and a glass container
take your glass container and pour some dry ice pellets inside
then add the alcohol to make some homemade liquid nitrogen
use the pliers to dip your gummy worms inside the liquid nitrogen
this should solidify them very quickly
make sure they are fully submerged in the solution
let them sit for about 30 seconds to a minute
careful you don't get any of the solution on your hands then use the pliers to carefully
remove the worms you'll see that if you try and bend them by hand they snap in half
now let's see what happens if we hit them with a hammer
they shatter like glass isn't that amazing if this is going to get messy we'd better take it outside
and there you go some more awesome dry ice science thanks so much for watching i hope
you enjoyed the experiment don't forget to check out our channel for more exciting
science videos where you can also leave us any comments about things you'd like to see
bye for now today i'm going to show you some more awesome dry ice experiments for this first
one you're going to need a bag of dry ice a large plastic container and a jug of water
pour the dry ice into your large container make sure you wear gloves when you do this
and you'll see that it very quickly fills up the container with mist
now let's pour some water inside and you'll see the reaction starts very quickly
add more water and it will increase the reaction look at that mist go it looks quite creepy
make sure you do this in a well ventilated area it's
best to do it outside where there's plenty of air
although don't make the same mistake i did and wait for the weather to get warmer first
you'll notice that when you go outside the wind blows the mist in all different directions
instead of letting it sink to the floor
the great thing about a clear container is you can see the reaction happening inside
now let's move on to the dry ice geezer
you'll need a plastic sports bottle some dry ice and a jug of water
this is an easy one simply remove the cap put in some dry ice add water and then replace the cap
once you've screwed the lid firmly back on open up the neck and watch the mist pour out
doesn't that look cool this one really looks like something that belongs in a mad scientist's lab
now let's make some dry ice rings you're going to need a plastic cup a rubber band a sharp
knife a cup of dry ice some water and some cling film take your knife and your plastic cup very
carefully with adult supervision make a small hole in the bottom of the cup it needs to be
quite small just big enough so that a pen can fit through then pour some dry ice into the cup
put some of the cling film over the neck of the cup and
then use a rubber band to keep it safely in place
turn the cup upside down and pour a small amount of water inside
this will start your reaction you'll see the mist start to form
look at that it's like a volcano going crazy
now let's try and make some rings very gently squeeze the cup
and look at that it's dry ice rings isn't that awesome it actually looks quite creepy
try it with a few different cups and try making slightly different sized holes in the bottom
and you'll see that it changes what the rings look like with a bit of practice
you can make awesome smoke rings like mine
and there you have it those are some awesome dry ice experiments thanks for watching i hope you
enjoyed them don't forget you can check out our channel for more exciting science videos where
you can also leave us any comments about what you thought or about things you'd like to see
bye for now today we're showing you some brilliant dry ice experiments for this
first one you're going to need some dry ice some balloons a large plastic bottle and some water
first tip some of the dry ice pellets into the large bottle make sure there's a good amount
in there so you get a strong reaction then carefully pour some water inside the bottle
very quickly you'll see mist start to pour out that's the reaction taking place
then fetch one of your balloons and stretch it over the neck of the bottle
now stand back and watch
the balloon will grow and grow and get enormous
until it can't grow any bigger
and then it pops now let's try the dry ice levitating bubbles you'll need some bubble mixture
a large bowl some dry ice and some water pour the water into your bowl
then pour the dry ice into your bowl and watch the reaction start
then blow some bubbles from the bubble mixture on top of your dry ice
and you'll see that they seem to bob up and down on the surface don't blow too hard or you'll blow
them away but you have to blow them just hard enough so that they land in the right place
this is a really cool experiment and a great one to show your friends
now let me show you how to make a dry ice popsicle you're going to need a slab of dry
ice like this one some lolli sticks and some juice bottles place your slab flat on the table
and then lay some popsicle sticks on top so that you can make your own
using a metal object like this you can draw around the stick to get an idea of the shape and then
scrape away at the dry ice holding a metal object against the dry ice for a while will make it melt
carry on with this until you're satisfied that your lolly mold is big enough
then pour a small amount of juice on top of the dry ice
you'll see that it doesn't react the normal way to how a liquid reacts on a solid surface
it'll start to bubble a bit
once you've filled your mould you can lay the lolli stick on top and set it in the right place
you'll make a bit of mess but stay with it
for this one i'm making two different flavors strawberry and apple
the very cold temperature of the dry ice will freeze the lollies very quickly
as the liquid freezes you might have to top up the juice a little bit to make sure your
popsicles are nice and large after a couple of minutes you can return and enjoy your ice lollies
simply dip them into a glass of water so that the outside temperature isn't too low
and then you can enjoy your delicious homemade dry ice lolly
thanks for watching i hope you enjoy these experiments please come back next time for
some more exciting science videos and don't forget to check out our channel where you can
also enjoy more experiments and let us know what you thought see you soon today we're going to be
playing with dry ice i'm going to show you a series of experiments that you can do at home
look at that isn't that cool for the first one you're going to need a jug of water a large bowl
a cloth and some washing up liquid dip the cloth into the washing up liquid and let it soak
then fetch your bowl and put a piece of dry ice inside
pour water over the top and you'll see mist start to form very quickly
then take your cloth out of the washing up liquid
and gently rub it around the edge of the bowl this will help you make your giant dry ice bubble
open up the cloth and very carefully pull it along the length of the bowl
this is a bit tricky but stay with it let me try that again and there we go now let's watch
look at the bubble grow it looks fake but i assure you it's completely real
the bubble will grow and grow until eventually
it bursts and lets all of the dry ice escape in a cloud let's watch that in slow motion awesome
let's try that one more time this one's even bigger look at it wobble it looks like a jellyfish
and when i try and touch it the bubble bursts
never mind
let's try another experiment this one is called boo bubbles you're going to need some washing
up liquid a jug of water a cup of dry ice pellets and a long plastic tube you'll also need a cloth
now let's get started making sure to wear a glove pick up your container of
dry ice scrape off some of the frost and pour it inside a large plastic container
then pour in a small amount of water and see the mist begin to flow
replace the cap on the container with your plastic tube inside it
dip it into the washing up liquid and there you go
you're making loads of tiny bubbles of dry ice if you dip the cloth into the washing
up liquid the bubbles will sit on top of it like magic except it's not magic it's science
now let's make some dry ice soapy bubbles
you'll need some dry ice washing up liquid water and a glass container pour
a good measure of dish soap inside your glass container this will help you make your bubbles
pour in some water to thin out the mixture make sure the water is hot
stir the mixture together and you're ready to go on drop the dry ice pellets inside and watch the
dry ice reacts with the water creating mist but it also creates bubbles that trap the mist inside and
so you get a continuous stream of loads of small bubbles filled with mist let's try popping some
wow that's crazy
i love experiments like this they're so much fun
and look at that reaction it's brilliant why don't you time this and see how long your reactions last
it just keeps going and there we are some really cool dry ice experiments
