The best way to learn not to be on fire is to end up on a little fire. Not a lot of fire. You know, not medium fire, just a little splash of fire. You know one way or another you're going to respect it at some point

We were... not entirely successful. But my son & I attempted to build a simple fusion reactor as a school science project...
(The hard bit isn't the reactor; it's the neutron detector so you can prove fusion has occurred)
