Thanks for posting this instructional video! My son used this to enhance his science fair project.

Hi. This is awesome but i really think you should make a list of materials somewhere.

A lemon battery doesn't generate sufficient power to make most lightbulbs light. Connecting a long string of lemon batteries might work, however. Let me know if you try it, and how it turned out!

If the clip is on the correct answer, the bulb should light. If it's on the wrong answer, the bulb shouldn't light.

I've never tried it with cardboard. It seems like it might be a bit flimsy, and I'm not sure how well the parts would stay in place. If you try it, please let me know how it worked out.

You need to put a materials list

how many screws?
