This is an open ended activity. I simply left the foam blocks and spray bottles in our big shower as an invitation to play.
The two 3 year old cousins had a blast with the water spray bottles and foam blocks. They were just spraying and sticking away! This is great practice for those hand muscles! Also, thinking and planning skills: where to spray the water, how to place the block, how long to keep it until it sticks etc.
You don’t have to play in the shower though, any glass door or window will do!
