Hello and welcome to HooplakidzLab making science super fun and super simple
Today we are going to make the volcano of vinegar
You're going to need a tin tray, vinegar, a jug, a jar, some red food dye, a piece of
paper, expandable foam, bicarbonate of soda and glue
the first step is to take your tray, take your jar and then get your glue
what you need to do is to use the glue to make a sticky surface pretty much the same
size as the bottom of the jar right in the center of the tray
once that's done put the glue to one side and fix your jar to the center of the tray
you need to give it some time to try while that's happening, shake up your expandable
foam you might have to do this 20 or 30 times
then start to spray around the base of the jar
rotate the tray with your other hand nice and slowly till you get an even amount of
foam on every side of the jar what you're trying to do here is build up
a surface of foam around all sides of the jar
we want to make our volcano as cool as possible so you might have to do a few coats of spray
to really build up that surface you might even need to let it dry for 20 or
30 minutes between each coat once you've done that and created a volcano
you're happy with you can decorate it like this one I made earlier
doesn't it look great? you can see with this one that I've painted
it brown for the rocks with added some red at the top for some cool lava effect with
even added some green at the bottom to make it look like tiny trees
the next step is to use your piece of paper to make a cone
place that into the top of your volcano then take your bicarbonate of soda and pour
in 2 to 3 table spoons once that's done, put the paper to one side,
grab your jug your food dye and your vinegar
pour few drops of the food dye into the jug it really doesn't take much
and then add the vinegar if you got a squeezy bottle like mine, this
might take a little bit of time what you want to do is end up with around
300 milliliters of vinegar then very slowly pour the mixture into your
volcano and BOOM!
there we go! your volcano starts to erupt
isn't that awesome? It looks really really cool
but why does it work? well, it's a very simple chemical reaction
the vinegar reacts with the bicarbonate of soda and created carbon dioxide
which forms bubbles and expands erupting out of the liquid
if your reaction starts to slow down you can pour a little more vinegar into the
volcano and you'll see that it reacts again
this a really fun experiment and it looks awesome
you don't need to decorate the volcano as much as I have
but I just thought it'd look really really cool
and there we have it, this was the "volcano of vinegar"
