Can a homemade RC boat actually float?

Can a homemade RC boat actually float?
In this video, I tried building an RC boat completely from old and recycled materials, no fancy tools, no expensive parts, just creativity and patience. The boat’s body was made from leftover foam board, powered by two small DC motors, and controlled using an old RC car circuit. I even used antenna tubes as motor shafts and 18650 laptop batteries as the main power source.

Everything in this build came from used or broken electronics. I connected the motors through relays to increase current, built a waterproof power box with hot glue, and used a simple 2S battery pack with a protection circuit to keep it safe.

It’s a small but fascinating project that shows what’s possible when you mix DIY spirit with recycling! Watch till the end to see whether it really floats — or sinks!
