This is primarily conceived as an outdoor toy, but if you do play with it indoors, clean up is fairly easy. Allow the solution to dry and vacuum up.
The way these work is that the booger bath interacts with the booger solution to create a kind of skin on the exterior of the booger balls. The longer they stay in the bath, the more the solution will set. For best--and slimiest--results, you want it to set long enough so that it's easy to throw and holds its shape but not so long that the booger balls harden. They will, however, make a hard floor slipper, so, really, use these outdoors.
We found that the best results come from making a big batch of them at once and then using them fairly quickly before they harden.
These really are non-toxic, non-staining and biodegradable, so you won't have to worry about clean up outdoors.
We talk about these a lot as "allowed naughtiness," which is a good thing for kids. It allows them to play with the concept of pushing the envelope about what's socially acceptable without doing any harm.
Refill sets and additional sets are sold separately.
Gross humor rules...at least sometimes.
