You need sponges (lots of colors make them more fun, I think), zip ties, wire cutters, and scissors.
Cut up the sponges into four long strips:
Take 8 of the strips and stack them in two's so you have a nice pile. (This picture does not actually show a pile, I forgot to take that picture.) ;0)
Place a zip tie around the middle of the stack and pull it as tight as you can.
Use wire cutters (or nail clippers) to cut off the extra zip tie. And that's it!
We had around 20 sponges to play with!
I filled bowls full of water with the sponges in them & let the kids go get them & either throw the sponges at each other or squish the water out of them onto each other.
I think the kids all had fun and we can even save them for next year!!
