RE: Hot Wires! (STEM toy for my girl.... and maybe me...)

Have some experience playing with this one with a young kid. The one with the sounds is very fun to annoy adults with. :)

The experiments that use the cardboard cut-out pieces are the trickiest to pull off. Need a really flat surface. One of them I recall launches a ball or something, and we found a way to make it send it flying across the room.
