Hydrogen Fuel Rocket

I like this.

I can’t say I ever put together rockets and set them off when I was younger, I can’t say I was never interested in it either. I did like blowing up stuff and I did build a potato cannon and shot potatoes at dumpsters. At about 30-40 feet, the potatoes tended to disintegrate when they smashed into the dumpster. Probably like the space probe did when it smashed into that comet today.
