I liked this story because I have read other Andrew lost books and I really like them.
It is about two cousins named Andrew and Judy. Andrew wanted to shrink himself to study ants. They are trying to get out the bathroom. Andrew has this machine in his pocket called the Umbubble it' s like a peice of gum. Andrew started to chew the umbubble and it started to get harder and bigger. Then the Umbubble was big enough to fit Andrew in it.
I liked when they were almost going to fall down the drain.
