I made these for summer a few years ago and they were a hit. They last for a little while but will eventually fall apart but you will get a lot of good use out of them before they fall apart. They can get kind of spendy, even if you buy your sponges at the dollar store. It all depends on how many you decide to make. The kids have a lot of fun with them though and it is a fun alternative to a water activity for the kids during the summer.
