What is on the wall and what are the kids playing with?

Ok, it looks funny, but it is a fun, creative, new toy: bendaroos. They are wax covered yarn. Silly but the kids love them. They are also called Wiki Stix- another brand name. They are kind of expensive for their simplicity but a quiet toy with no mess is priceless and they are re-usable! The art they make can be stunk to the wall or window, so if you notice funny things stuck to my wall it's the kids creations on display. Or if you see them playing with silly looking strings, they are bendaroos. Oh, they are nontoxic and don't taste like anything. They are also water proof if you happen to spill your drink on them. Yes, we have learned lots of things about them.
