Sorry there are a "kazillion" pictures here but this was the first year I have done this experiment and it was so awesome! We made magnetic goo! We used glue, water, liquid starch, and iron oxide! The goo was fun to play with on its own but the most incredible part was when it would come close to a magnet. It would consume it slowly but quickly enough to hold our attention! Hopefully the kiddos enjoyed it as much as I did!
