Looking For Kid-Friendly Chemistry Experiments

My 5-year-old nephew, Daniel, will soon spend his first full night at our house. In preparation for the big day/night, I am looking for fun activities to keep him occupied. I remember how much fun my brother and I had over my grandparent's house when my grandpa would take us to his workshop in the basement. He would set up fun experiments and we would feel like mad scientists. I want to create the same fun for Daniel.

In the summertime the neighborhood kids always get a big kick out of the Mentos candies in the bottle of soda trick. But since it is the middle of winter, I don't want to do this inside for myriad reasons.

So my plea to you, Chemical Reaction audience: Please share with me kid-friendly chemistry experiments that won't require a trip to the ER or a call to the fire department.

Thanks in advance!
