This kid continues to amaze me with his creativity. This is a "device" he made the other day. The base is a motor that spins around. This is from his K'nex sets. He then attached a K'nex straw to it. At the very end, he had wire attached to a butterfly (fake, obviously) that he found. He secured the whole thing to the ceiling with tape. Once turned on, the butterfly spun around and around. He made it especially for me.
