Disected mine apart as instructed...
Left on table and went outside to water the plants and yard...
An hour later when i walked back in the house, found out that my soon to be 2 year old daughter was as intrigued by all the parts as i was...but she put some in the trash...some in the toilet...and some i just can't find...
Long story...short...
No enough parts to finish this experiment...
