Make a bottle disappear in this science experiment you can try at home
When you place a mini bottle in a glass of water, it looks pretty normal.
But when you put fill the bottle and glass with glycerin, it looks like the mini bottle isn't even there — you can see the pencil behind the glass set up isn't distorted at all.
This is because light travels through glass and glycerin at the same speed, so your eyes don't see a boundary where the bottle is, rendering it invisible.
Glycerin is a liquid that is sold at most drugstores as a skin softener and protectant. It used to be made out of animal fats, and was typically recovered as a byproduct of soap. But today it's normally made out of palm kernel oil.
The colorless, sweet liquid can also be used to make nitroglycerin, the explosive ingredient in dynamite.
