Egg Project 2: Annie’s 6th grade class must use wax and an egg shell to create a water storage vessel, like nomads in the desert. Having done it for Alex two years ago, we’re experts. Finished in 15 minutes. Made two (heir and spare) in case of accident (Alex dropped his first one).

Tricks: make two holes large enough for a straw (easy to blow out the egg and refill with water), use multiple coats of wax around the holes.
