Hydrodynamic bearings are really cool! The Kingsbury aerodynamic bearing is a brilliant example as is an ordinary glass syringe.
A huge thank you to Tom Lipton for making the bearing. Watch his making video here:

Anesthesiologists use a glass syringe when placing an epidural for regional anesthesia. The anesthetic for an epidural needs to go into a very specific space near the spinal cord called the epidural space. The anesthesiologist advances a needle into the back with a glass syringe on the needle. Each time that the needle is advanced, the anesthesiologist lightly presses on the plunger and releases it. Because of the low friction in the glass syringe the plunger readily springs back if the needle tip is not in the epidural space. As soon as the needle reaches the epidural space, the plunger goes all the way in with no spring-back. A plastic syringe doesn't work for this, because it has too much friction to respond the same way.

Amazing video. Very well explained. I had no idea there are glass syringes! Crazy.

Years ago, i worked in a potato chip factory. There was a single machine that peeled the potatoes by tumbling them over a series of shafts which were surfaced with brush bristles. The bearings that supported those brush shafts needed a lot of maintenance and we were using food grade grease to lubricate them. The grease would get washed away by the water, abrasive potato rind and inevitable amount of dirt that was present.
I made the suggestion that we adapt the bushing type support bearing by injecting water into them. This virtually ended the maintenance cycle since there was no longer any contact and the water flowing through kept the new bearings clean.

There was a very interesting CPU cooler concept out a few years back called the Sandia Cooler, which used this air-bearing principle. They thought the barrier was thin enough to still be thermally conductive and you could spin a plate that acted like a heatsink and a fan in one piece, at low friction. Cool idea, and Thermaltake tried it out with their Engine 17 and 27 coolers. But they weren't as effective as hoped.

this is really good. Steve has really found his style of presenting. I love the honesty in his interest and his reaction to things.

Hey Steve. Great video! So what's next?
Cheers,

I am seriously impressed with the professionalism of this channel. The manner in which Steve presents scientific material without losing my interest is applaudable. It is as if he has taken several bite-sized appetizer clips and cleverly combined and edited them into a full course meal in a very satisfying way. The sweet spot is between being oversaturated with information and being deprived of details pertinent to grasp the context. That sweet spot of captivation is where this channel lives and why I subscribed. I think this is my new favorite channel

I really love when great YouTube minds I've come to enjoy collaborate. The science of why on one end and the functional how to on the other. Great job as usual. š

I love how you can make amusing science content from the simplest, most mundane everyday objects. I wonder how you come up with these ideas, whether you scratch your head and do research or just look around your room and say "hey I can make a video about this random object"

Steve Mould saying BOIOIOINGGG for 10 hours straight.

This was very interesting. I absolutely love this stuff and Thank you so much for introducing me to Tom Lipton's channel.

I have to rewind several times to understand the concepts clearly YouTube is awesome and also Steve mould.

The good old VCR created an air cushion between the reading head and the tape. The rotating head has spiral grooves which transport the air under the tape.

Gauge block wringing absolutely blew my mind, I can't believe I've never heard of that before

I've watched Tom Lipton for years now and it never ceases to amaze me just how skilled he really is. He's what I would consider to be a master of his craft, but he's too humble to admit it. And that happens to be another reason I like watching his content. You know he's extremely skilled and knowledgeable but he's in no way pretentious about it.

Great video, I love learning new things. I'm just curious if you tested to see how long the glass syringe would maintain its volume before it trickled out?

Amazing!!! I have had a jab from one of those glass syringes in my toddler days. But I never knew that the same glass syringe spins. You are amazing. Keep going on with such inspiring videos.
