We've spent the afternoon dissolving, melting, blowing, and smashing. I've got a whole week's worth of experiments to show you.
We always love playing with Warheads, which make the very most bubbles when we dissolve them with baking soda. Today my son experimented with whether to drop the baking soda in the water before adding the Warheads, or after. His verdict: if you mix the baking soda in after the Warheads have started dissolving, you can trap bigger bubbles at the surface. The Warhead glaze must form some sort of film on the surface of the water.
