Artopia is a really nice place to take the kids to do some ceramics. The pieces can be glazed afterwards, and they turn out really nice. If you do not want to wait a long time for the ceramics ( it usually takes around 1 - 2 weeks) then you/ your kids can paint some wooden things or some glassware. Whatever you chose, it'll turn out great, I'm sure. But be sure to check the price tags before ordering.. those little things can turn out to be really expensive!
