Clayotic

Clayotic is a brand of non-toxic, air-hardened modelling clay sold by the Irish company of the same name. It is created for young children to sculpt figures like regular clay. Clayotic comes in several different colours which can be mixed to make others. According to the company, it is a mess-free Play-Doh. Once Clayotic is exposed to air long enough, it dries and becomes hard.

Similarities
Clayotic is similar to Hey Clay, Model Magic, and Jovi due to its air-dry-clay like nature. Once it hardens, it is no longer able to be molded. The only way to get it back is by chopping it, putting it into a bag, and left for two days.

Etymology
"Clayotic" comes from clay (relating to its concistency) and chaotic (relating to the creative minds of the child).
