When the B-Man and Mater spent the night with us at the beach, we had some crafty water fun. We made these sponge balls (which I forgot to take a picture of) to play with in the pool/ocean/bathtub. Super easy and all you need is kitchen sponges and dental floss! We had a blast throwing them at the Rev while we were in the pool!
Then I let the boys mix up their own bath paint. Again few ingredients - just cornstarch, baby wash, and food coloring (recipe here) and as you can see they had plenty of fun painting the tub walls and themselves! And no worries, it all rinsed off with plain old water.It was a ton of clean, cheap fun!
