What you need:
A pack of hydrogenated vegetable fat (vanaspati), a small bucket, a bag that can be sealed that is big enough to cover your hand, another bag of the same type that can fit into the first, ice, cold water, duct tape
What to do:
1. Half fill the bucket with cold water. Now add lots of ice to the bucket. This ice bath is meant to represent the wintry polar waters.
2. Into the first bag, drop three big spoonfuls of vanaspati
3. Put on the second bag like a glove.
4. Now, shove your ‘gloved hand into the bag of vegetable fat. Pat it with your other hand so that the vanaspati evenly covers the hand inside.
5. Ask a friend to fold the top of the inner bag over the top of the outer bag and duct tape it so that the vanaspati doesn’t leak out.
6. Now, push your gloved hand into the ice bucket.
What happens:
Your hand doesn’t get cold at all!
Why?
Fat is the clue. Animals such as whales, seals and walruses have body fat known as ‘blubber that keeps them warm in the frigid polar climates they live in. This fat traps the heat and doesn’t allow the cold to get in. That’s exactly what your vegetable fat glove does too!
