- Get 5 cups and pour 100ml of scorching water into every one.
- Add two sugar cubes to the primary cup, three to the second, 4 to the third and so forth.
- Add meals colouring to every cup to make one pink, one blue, one inexperienced and so on.

A phrase of warning on this one: there’s a uncooked egg beneath the membrane and for those who bounce it too laborious, it’ll pop and also you’ll find yourself with uncooked egg in all places.
It’s principally human nature to maintain bouncing the egg till it does pop, so my feeling is that for those who make the bouncy egg, you’re going end up cleansing up uncooked egg at some stage.
