The foam is a model of a real cloud: it soaks up colored drops until it can’t hold any more, then blue streaks fall through the water like rain. Squeezing a dropper one drop at a time also strengthens the small hand muscles kids later use to hold a pencil.

The steps are in the app

Step-by-step instructions, tips and an easier and a harder version are waiting in the Hopsa app – along with 300 more ideas matched to your kids’ ages.
