Overall, it was okay. The kit comes with the pieces to build the toy toilet (one out of four colors with stickers to decorate it) and two flavored powders (I got cola and strawberry).
You use the lid to measure water to put into the tank, put one of the powders into the tank, and shake it up while holding the lids closed. Then you use the straw that's included to "drink the fizzy candy from the toilet bowl. The cola was okay, but the strawberry was better.
