Tank Plant - Capacitance

Building it together with my son was surprisingly fun, and I loved how the capacitance lesson actually stuck with him after just one play session.

My kid spent a solid hour figuring out how the capacitor makes the plant light up, and honestly I got sucked in too. It's a clever little build that actually teaches something instead of just blinking once and getting boring.

The tank shape is way sturdier than I expected for a hack pack toy, and the capacitance gimmick actually got my nephew to sit still for an hour. He's already asking for the other ones in the set.
