i know it's way too late now. But the issue with the first attempts at the steam cannon is not the temperature but the Thermal Mass in my opinion. Water takes tons of energy to go from Boiling point to steam. And having a thin walled Tank just doesn't provide enough mass of metal to store sufficient energy without getting really really really hot. Going for something like a reverse heatsink, like a bigger block of Copper (like 20 times the mass) and heating that up would probably worked a lot better at turning the water into steam. Like doing some quick math: You'd need around 3.2kg of Copper at 150 °C to bring 200g of water from 25°C liquid to 100°C steam (~520kJ). And that would assume perfect instant energy transfer, having a more massive tank of copper that is thicker would give a much better margin to deal with losses and inefficiencies in the Energy Transfer and ensure a better vaporization of the Water.

Who would have thought a fuzzy tennis ball wouldn't fly smoothly through a roughly milled wooden tube?

You can see Jamie Lose a small piece of his soul when the expert tells them their steam cannon would work "if it's properly engineered."

You could have used some math to see the specifuc heat capacitance of the metal vs the water in relation to their respective weight and see what delta temperature you would be looking at. Most likely they are only cooling the pipe with the water to produce a minescule part of the water into steam. You need about 4180 joules to heat a kg of water only 1 degrees celcius. Not to speak of how much energy it takes to get water from 99 degrees C to steam

4:04 Remember, M5 is Jamies shop. That's his stuff. A lathe isn't just an expensive tool, it's also a tool that creates a lot of dirt AND can take your head off if you lose control. Which is what Adam nearly did. Adam showed off his lathe in his own shop in Tested and made it very clear that doing something like leaving the chuck key in and turning it on would result in instant and permanent banishment from his shop. Seems like he's less careful when it's not his stuff he's potentially breaking... Or he can't control his frustration and goes off to do something else, leaving the smoldering remains of his failed attempt for someone else to clean up.

It's been almost a decade and a half since this happened back in M5 so Adam surely has so much more experience, and hence more caution, now in Tested.

it's very odd to me how they've chosen a tennis ball for this. feels like the sort of decision that was made AFTER the thing was already built. the only available light ball with that dimension or something. there have to be better options for a cheap light projectile than a rough tennis ball.
