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.
