This is our trying to create a button for our circuit. At first, we thought about making two birds using tinfoil and once the two birds get into the same pool, water can help to finish the circuit and light the led light.

But when we tried to put the birds into the pool, it seemed like the water cannot be conducted so the two birds have to meet and “have a relationship” in our scenario.

Another thing we found is that the birds we made are too heavy to float on the surface, so we made two boats later for them to stay on the surface and meet with each other.
