Challenge: Design a more powerful battery

My penny battery is powerful enough to light a red LED but I have a blue LED here.

When I attach it, it doesn't light up.

Can you design a penny battery that's powerful enough to light a blue LED?

Here's a hint; blue light is a higher frequency than red light, and so requires more energy.

In the next video, I'll show you the solution I came up with.
