My 9 and 11 year old daughters, and to some extent my son, have gone off the charts with turning our kitchen into a chemistry lab and concocting slime batch after slime batch. The youngest has become an expert with "superpowers". All the colors of the rainbow, some with sparkles, some clear, some adding modeling clay and the list goes on and on. Now all we need is more tupper ware to hold it all, well and for food also, considering the current TW is all  "slimed". She wanted this t-shirt to proclaim to the world her Slime chemistry superpowers and all those who would like to do the same.
