Usually kids love pool noodles. The noodles are fun for a lot of reasons. It is easy to grab them and float around the pool with them. It is also fun to fill them up with water and blow it out on someone else. That is not their intended use, of course, but it does not stop it from being fun. Also, I've seen plenty of kids smack each other with those noodles in the pool. They are fairly soft, so there is really no harm in it.
