  1. You could go 288 mph assuming you don't hit a pebble before you get to that speed.
    Or am I dating myself? The poly wheels were just coming out when I was a kid. They were worlds better than the old wheels but we still had the "pebble of death" problem.
    Have they solved that problem with modern wheels or are there still kids with nasty road rash because they hit the pebble of death?

  2. Did you ever try compressed air, or not using abrasive in the water so that you're not weakening the wheel as much? I can't help but wonder if it would do a little better without that channel cut into it.

  3. Spinning that high rpm the tire want to make a bigger C so you cut the middle it’s explode as the stress is on the cut

  4. I guys need a welder?
    Love ur vids and omg the “Lick test”
    Should send some THC infused things hhhahah

  5. Do just the bearing…I did a wheel bearing form a Dodge truck with just Air..with my finger in the center hole of the bearing when it disintegrated part of the bearing almost went through my aluminum garage door, and no it didn't hurt my finger at all but it was scary when it blew up it sounded like an m-80 going off

  6. And doing it on a metal bearing, the metal bearing will exploding hurting the water-jet. should experiment with different types of plastic/rubber compounds and better bearings so that isn't a problem.

  7. Didn't they use train wheels (locomotive)in the rocket car test in the desert, to break the ground speed record

  8. You're not stupid but I don't see how this is a valid test of the actual spin rate a wheel can withstand since the force isn't being applied at the center of the wheel.

  9. When they expand the jet is what cuts it and breaks it. It's not spinning and exploding. You can see on the red wheel real well. Once it expands out the jet cuts it.

  10. The most interesting thing to me is that that bearing is probably an ABEC class 7 bearing. I've purchased these bearings before for use in small precision spindles,… These bearings are extremely precise bearings (look them up) and they use them in skateboards.

  11. 𝔂𝓸𝓾 𝓷𝓮𝓮𝓭 𝓽𝓸 𝓶𝓸𝓿𝓮 𝓽𝓱𝓮 𝔀𝓪𝓽𝓮𝓻 𝓳𝓮𝓽 𝓫𝓪𝓬𝓴, 𝓪𝓼 𝓽𝓱𝓮 𝔀𝓱𝓮𝓮𝓵 𝓮𝔁𝓹𝓷𝓭𝓼…𝓸𝓽𝓱𝓮𝓻𝔀𝓲𝓼𝓮, 𝔂𝓸𝓾 𝓳𝓾𝓼𝓽 𝓬𝓾𝓽 𝓽𝓱𝓻𝓸𝓾𝓰𝓱 𝓲𝓽 ✌🍩

  12. Realing great to see the effect. Those bearings ,I think you can buy them by the bundle at like home depot or Menards. You should make wheels from different materials,, wood, plastic, etc. Could be interesting.

  13. Neat concept/test. It seemed like the spray obscuring the view was rebounding on the wood just below the wheel. If the stream was free to spray on past the wheel maybe it would be a clearer view. Anyway, thanks for posting.

  14. Try the same test only use a second wheel for the water jet to drive the RPM.s and the other wheel can just spin without the water effecting it. I think the water jet was causing some of the issues especially when the wheel expanded. Use a metal wheel as the drive wheel and mount the test wheel on the same shaft. I also saw the axle moving around and wobbling. Use a stronger axle and bearing set up. Use 2 mounting points so the wheel and axle is supported on both ends.

  15. As the wheel expands, the jet is no longer at the very edge and starts cutting deeper, causing it to weaken and explode before it reaches max speed. Theres nothing you can really do about it though.

  16. I cant beleive you would harm a cute littleParasaurolophus by leaving him in that dirty okd murky water to be trapped for 2 months and not get washed at all i mean seriously why?(Before you start hating, hear this. I have always been a huge fan of dinosaurs and any animals or toys slash stuft animals so when I see any harm to any cute animalistic creatures I get upset.)

  17. Well, you guys might have just saved a life. I was planning on setting the skateboard land speed record in the spring breaking 300 miles per hour. Can you imagine the outcome had I not known that they wheels would explode at 288 mph?? Scratch that off my goals list. I'll be sticking to around 250 mph like normal from this point on.
