today we're going to show you how to make a fire water balloon doesn't that sound weird
all you're going to need for this experiment is a funnel
a glass of water a lighter some balloons and a candle
the first step is to carefully take your lighter and light your candle
make sure that you have a parent or another adult with you when you're conducting this experiment
the next step is to blow up a balloon carefully tie off the end to make sure no air escapes and
hold the balloon carefully just above the tip of the flame as you lower it down you'll see that the
heat from the flame pops the balloon and the force of that air escaping actually blows the candle out
so how do we stop this from happening well here's the trick take the funnel place it
inside the neck of the balloon and fill up the balloon with water not too much just enough to
fill up the balloon as it is once you've put the water into the balloon very carefully
blow the rest of the balloon up until it's about the same size as the first balloon then once again
carefully tie off the end of the balloon to make sure none of the air or the water escapes
once you've done that you're ready to proceed with the experiment
once again very carefully light the candle place it on the counter take your balloon and hold it
the same distance away from the candle you'll find that you're able to get much much closer
to the flame and still nothing happens the reason this happens is because the water
inside the balloon is conducting the heat away from the surface this means that it doesn't pop
you can very slowly and carefully move the balloon around above the flame and you'll
find that it still doesn't pop and that's because the water moves with the surface of the balloon
you'll find that you're able to hold the balloon above the candle for a really really long time
and absolutely nothing happens and there you have it that's how you make your very
own fire water balloon at home today we're going to show you a non-popping balloon
now this is a really fun experiment that you might have seen before all you're going to need is a
roll of sellotape a skewer and a balloon all you need to do is stretch out the balloon a little bit
and then blow it up just as you would normally
once you've blown it up very carefully tie one end off or have a parent do it for you make sure
it's completely sealed then take a small piece of tape and fix it to one side of the balloon it
down nice and firmly then turn the balloon around and stick a piece of tape onto the opposite side
this will mean that you have a piece of sellotape on either side of the balloon
then take your skewer and very carefully very slowly push the skewer through the balloon you
might want to try twisting it slightly just as you do this you'll see that the skewer goes
all the way through the balloon without the balloon popping this is because the surface
of the balloon is made of rubber which tends to cling very tightly there's already surface
tension in the balloon because you've blown it up and so when you push the skewer through the side
the rubber clings and sticks to the outside of the skewer meaning air is not able to escape
and there you have it that's how you make a non-popping balloon today we're going
to show you how you can fill up a balloon with a chemical reaction what you're going to need to do
this experiment is one tablespoon of baking soda quarter of a cup of vinegar some paper a bottle
and a balloon first of all you need to take your paper and roll it up into a cone shape
here we go easy peasy so just put it into the top of your balloon like so
and pour in the baking soda
then very carefully remove the cone from the top of the balloon
and stretch the neck over the top of the bottle make sure you're very careful when you do this
then take the other end of the balloon and tip it upside down this will pour the baking soda into
the bottle and you'll see the balloon start to fill up instantly this is because the baking soda
is mixing with the vinegar and creating a gas called carbon dioxide which fills up the balloon
and there you have it your balloon filled with nothing but a chemical reaction this is a really
fun way to blow up your balloons so next time you have a party at your house or you have a birthday
maybe you could blow up all your balloons this way please do share this video with your friends

doing the experiment today we're going to show you the balloon trick you're going to need a balloon
and some pins as well as a flat surface as you know if you push a pin against a balloon
it pops it's really loud and it can scare people but what if you used lots of pins
in this case we've emptied out a whole box of pins onto our table
you'll need to take a little time and make sure that each of the pin points is pointing upwards
it's best to ask an adult to help you with this make sure that they're grouped closely together
then take your balloon and nothing happens try pushing down again and you'll see that nothing
happens this is actually for a very simple reason when you push a pin against a balloon one single
sharp pinpoint creates a lot of pressure in one area which pierces the rubber and pops the balloon
however lots of pinpoints spreads the pressure against lots of different points meaning there
isn't much pressure in one single place meaning it's very very difficult to pierce the balloon
and there you have it that's how you can perform the balloon trick
