The Disappearing Egg Trick
Ask your child to watch this cool science experiment. Take a hardboiled egg and remove the shell. Find a glass bottle with a mouth just slightly smaller than the egg. Fold a piece of newspaper into a strip that fits into the bottle. Light the paper on one end with a match, insert the paper into the bottle, and place the egg on top. As the fire burns out, the egg will squeeze through the mouth and into the bottle!
