Was fooling with a 5-ml syringe once, decided it would be fun to block the end with my thumb and pull back on the plunger. When I released the plunger it sprung back and made a jolly sound. That was good fun, so I figured the same thing with a 60-ml syringe would be 12 times the fun. It wasn't - when the plunger hit the front of the syringe it drove the luer-lock taper into my thumb, cutting a perfectly cylindrical hole into my thumb. Bled like a stuck pig and took weeks to heal, and hurt like hell too. 0/10, would not recommend

@msmeyersmd8 4 года назад

Ben Stewart Maybe there’s cavitation in the condensed water that gives a huge energy boost with the 10cc syringe. With the high speed camera in total darkness he could look for blue/UV photon emission. Water cavitation creates an incredible amount of heat that results in photon release. I’m curious if that might be happening and resulting in a huge energy boost. I’m not sure of the mechanism of translating that into kinetic energy. So I doubt it. But I am curious?

@ritwikreddy5670 4 года назад

@@msmeyersmd8 cavitation directs the surrounding energy to a much smaller point, making it more effective in destroying the containers the vapour is in, but it doesn't produce energy of any sort. Since the syringe is an enclosed space, any cavitation if significant would only contribute to shattering of the syringe and not to its movement since its an internal force.

The atmospheric pressure is actually forcing the two pieces together not forcing the plunger up. If it was forcing the plunger up then the two pieces would remain more or less separated.

@davidvhoudt 4 года назад

I have had a project in which i made a 'compressed air bottle rocket'. i see that your blue projectile is indeed somewhat instable. However I had a problem with getting really far. When i shot an unweighted bottle it went fast, but lost alot of speed to air resistance. After a while i made a weighted bottle and that one went alot further. I suggest you look into adding (a bit) of weight to the projectile. Of couse if you make it too heavy it will not get the maximum amount of velocity. I hope this helps.

In the final version of the small syringe it is interesting to see the gas above the piston forming vapour clouds due to pressure drop as the piston oscillates downward and upwards after it reaches its maximum approach to the top of the syringe body at 10:32 an 10:40. Much like the vapour cloud that forms on lower pressure parts of an aircraft wing on a humid day.

I would think the air would hurt it more by converting kinetic to pressure and then just pushing the plunger back down instead of the tube up. 6:38 is a great example of what I'm talking about, you can see the plunger move back like 20% of the tube length.

Hey, I have a question for you. Why are pistons and their cylinders round? Why can't we have an engine with square-ish "cylinders" and pistons?

@akhilsubhash7644 4 года назад

I think it is due to structurual integrity because round shape spread the load evenly so that strong parts could be made without using more material

@SM-- 4 года назад

1) Stresses concentrate on the pointy corners of the pistons, eventually eating away the sharp corners and creating leaks. 2) Sealing a sharp corner is harder than a sweeping radius. 3) Machine tools have really hard time machining sharp inside corners, there's always a tiny radius left behind. 4) Lathes and boring machines make it easy to create precise cylindrical shapes (only radius matters) where as square shapes require precision on two different axis (x and y). 5) There are very few advantages in other shapes (packing factor is the only one that comes to mind) Those are the ones that came to mind, of course there's more to it.

@tom_something 4 года назад

One potential limiting factor in the vacuum cannon rocket is the release speed of the plunger. As soon as there's any gap between the plunger and the body, air starts rushing in, but slowly. So you want that gap to open as quickly as possible, increasing the gas flow rate which increases the pressure, which increases the force on the projectile, and since the distance of the projectile is sort of fixed, increasing that force is the primary way to deliver the maximum amount of work, energy, into the system.

@morphman86 2 года назад

An excellent demonstration of how it's not the vacuum sucking, but the air pushing from the other end. If it was a suction from the vacuum, the syringe would not go flying, as equalized energy would be achieved as soon as the vacuum is gone. You can try this yourself with a rubber band and just about anything light enough, like a piece of lego. Stretch the rubber band, place the lego in the path of the rubber band and release. The lego goes flying. Now stretch it again and place the lego right at the point where the rubber band is no longer contracting. The lego barely moves. This is because all the energy has already been expelled at that point and there is nothing left to transfer over to the lego.

@RWBHere 4 года назад

Thanks Tom. Vaseline will act as a sealant and lubricant for that syringe body and plunger. Also, with the large tube, if only the top end separates, after being held in place by a diaphragm or other seal, then the plunger plus small end cap will go a lot higher than it would if you tried to launch the whole apparatus.
