For my Handless Switch, I chose to recreate a simplified version of football where the user must score a goal, using their feet, in order to light the bulb. In order to make the goal and ball conduct charge, I covered the two items in aluminum foil, which is known to be a conductor of electricity. 

Due to not having much experience with circuits in general, it was hard to visualize the process only using my brain. Therefore, it was helpful to draw a diagram planning the connections in advance before making the actual product as shown below.
