This website says that the water coming out of the jet can attain speeds of up to 600mph. Assuming that the wheel is going at something closer to 400mph or ~180m/s (I doubt it would be going to full speed of the water), and taking in the size of a skateboard wheel (we are going to go with a 28mm radius and a mass of 0.1kg (based off an item on amazon)), than this thing is looking a centripetal force of ~125,000N, or about the weight of a school bus. That is also like ~70k rpm.

But yeah, the heat definitely contributed. That thing had to be hot as fuck.

Someone please check my math.
