How to Make a Bubble Bomb with Baking Soda and Vinegar

We are using again our favourite ingredients - Baking Soda and Vinegar - for a fun and easy science experiment for kids.! This fun and safe "bomb" will explode with a loud pop! Here is what you need and how this fun and easy experiment works.

You will need:
water
a measuring cup
a plastic zip lock bag
a paper towel
2 tablespoons of baking soda
vinegar

Step 1:
Find a place where making a mess won't be terrible - outside, or maybe in the bathtub if the weather's bad.

Step 2:
Test your bag for leaks. Put water in it, close the seal, and turn it upside down. If no water leaks out, it's OK to use.

Step 3:
Tear a piece of paper towel, about 15 cm square. Put 2 tablespoons of baking soda in the centre of the square and fold the paper around it.

Step 4:
Mix 300ml of vinegar with 150ml of warm water, then pour them into the plastic bag.

Step 5:
Put the paper towel package into the bag. Hold it in the corner away from the vinegar while you seal the bag.

Step 6:
Place the bag on the floor - and stand back! The bag will swell up....

Step 7:
.....and then pop!
