https://mocomi.com/ presents: Water in Plastic Bag Trick - Cool Science Experiment for Kids

REQUIREMENTS : -
Sharpened pencils
1 Zip lock bag
Water

HOW TO DO : -
Pour water in a zip lock bag from a jug. Hold the zip lock bag over a vessel, so that in case it spills, you don’t make a mess.
Now, poke a pencil through the middle of the bag. What do you find?
Poke another pencil through the bag and see whether you get the same result.
Finally, poke the third pencil through the bag.

WHY THIS HAPPENS?

The plastic bag is made up of long chains of molecules called polymers. This makes a plastic bag stretchy.
When the sharpened pencil pierces through the bag, these long chains of molecules seal around the pencils within seconds, thereby preventing a leak.

TRY THIS : -
Do this experiment with water in plastic bag trick. You will find out what happens. Wow your friends with this ‘magic’ trick! See if they can figure out why it happens.
