The goal of this channel is to help other educators use instructional technology in the classroom. Tutorial videos are usually very long and it takes awhile for someone to find what they need help with. My goal is to create 1-3 min videos that cover a specific tool, skill, or task. This way an educator can find exactly what they need help with or find something they didn't know they could do. I will cover topics on G Suite Tools, Screencasting, Video Editing, 3D CAD/Printing, STEAM based lessons, instructional technology reviews, and more will be covered on this channel.
Hi, first of all, thanks for sharing this knowledge. I'm buying a corn pump to inflate my balls. I have a few questions: * Is there a minimum number of balls to put inside? Or do you need to fully charge the corn pump each time? * I train once a week using around 20 balls. Will it work to maintain ball pressure between trainings?

Hello brother. Would you tell me how many times did they supported re-pressurization process? How did they feel on the court and how many games did they last after that
🤬😡😤What the actual !#%! His entire premise was about how none of the "other" vids let you know the outcome of the tank experiments...AND then he goes and does the same flipping thing!
Quick question for you. After you re-pressurized 32 psi the tennis balls, then how do you store them? Put them back in keg with 14 psi like the new can of tennis balls to keep them fresh? Thanks Jeff
As the air filters into the balls the pressure in the tank will drop, so for best results you should top off the tank every couple of days. Going over about 25 psi may cause some balls to collapse and they will not be filled, so starting with 25 psi for the first few days and then working up will reduce this problem. If you listen you can hear balls collapsing providing your compressor is not too noisy. If any balls collapse drop the pressure to zero and start over and don't go as high for a few days, then work up. Some brands of balls respond better than others. Occasionally balls left too long at high pressure will become super-bouncers and bounce higher than new balls, but they calm down pretty quickly as they are used.
Just a physics question: lets say the air pressure is around 15 psi and the regular pressure inside a tennis ball is 26, you would only need to add 11 more psi to bring it to equilibrium. give or take. I noticed that my pressure gauge starts at 0 PSI, which would be vacuum, not 15, aka air pressure, which means whatever the gauge is showing is additional psi to air pressure. In this case, we only need 11 PSI more? I understand the higher the pressure outside, the faster it will pressurelize the ball. Just wanted to check the physcis here.
Why does it lose air in the first place? Can't they add a thin layer of sealant or something on the inside to stop air from escaping..ever? Car tyres don't lose pressure except for puncture so why can't the same be applied to tennis balls? I just play tennis socially but I am burning through balls and it's getting pricey.
Thanks for the video and the results video too, it is a very good experiment. I wonder what if I just used my car spare tyre and inserted the balls inside to do the same exactly, what do you think? Thanks again
you should only add around 12-15 psi, or the ball will be too hard, I usally pump my canister to around 20psi then leave it for 6 weeks or more, some balls take even longer! Depends on the make, usally they re-inflate at the same rate/time it took them to deflate. Nice kit you made.
Sick video. How much do you think the thermal pads affected the lower temps? Or is that negligible? I'm thinking about getting a laptop with a 12900H, and people's reviews say that thing gets to 99 degrees immediately. Definitely going to tear it down from factory and replace it with some kryonaut.. Just wondering if replacing the pads is worth it? most people say these days, especially for a brand new pc, it's not.. but honestly, if it does make a difference, I will Thanks for your time.
You should try phase-change material Honeywell PTM7950. It comes in as a sheet, lasts longer and performs works better than traditional pastes. On the power section and vrams propose to give thermal putty Upsiren UX Pro. Also do undervolting on the CPU and GPU at -100mV or more if it will be stable.
just wondering, what if you put a thermal paste around as a perimeter fence and liquid metal in the center? the idea is that the thermal paste around will catch the liquid metal.
But it's still bad practice; in order to solve this probleb; one needs to solve both problems. Their is the bounce problem and the fuzzy problem; where these both create an environment towards a thing that I like to call"bad practice". You are better off not playing tennis if you aren't going to use the ball that will be used at the places where you will be playing against people that are your caliber and played with the same balls that you will be using for the match against you. There could be a way to keep yourself at logical of ratio if you were to use the new balls at intervals where you do practice with these in this video as to keep your witts about the habits that a new ball's reaction are upon spinning and the sound that it makes also should give you a heads up on what speed to expect it's coming. I've only had a segment of playing until we were starting to rally pretty good when I was 19 or so and without the fuzz; I don't know; I seem to kinda remember there being a difference but it also meant that the others were dead too. But ideal for the pressure would be an automatic thing and I could create that or tell you how if you'd like. I don't have the time to create anything that I figure out otherwise that would be all that I'd be doing and that isn't what I want to do. Cheers and give it a couple of days and I'll think of a few good ways. This was why I found this; because I checked if someone else thought of this but me I would had put a super tiny valve that would had let the air in quicker.
Ok so what I came up with is a choice between two ideas for now and one is to use that same liquid as the flat tire one use repair can but a more liquid if possible; or maybe FLEX dilluted with rubbing alcohol when I tried it to see if it would work but if you were to find the solvent for flex caulking and have it so it's almost like water; then injecting the correct amount would be Ideal; then you just play with it and it will fill all the pores and cure.I'm not sure but you may need to use a tiniest needle; if there are different siringe sizes. The second ideal wasn't as good or as easy and this next part was me writing it before and decided to give you these ideas prior to the reply because even though I wrote it before; it's something that would go better after; LOLOL whom cares right; of course. Cheers. You know what; one of these companies needs to make one that is airtight and that would solve your dead balls problems and for the fuzz there are things that could mimick; but cosmedically wouldn't be perfect but you could re-felt them I guess.
You could sell them in a container that is a three layer; where the outer layer's inner surface has threads that match with the outer surface of the middle layer and it's inner surface has seals that interact withe third layer's outer surface and then the balls return to the can (container)and now you screw the two parts together and the smaller the inside gets; the higher the air pressure it also becomes. There; that will be the last one. I am done like dinner. Cheers
Hola, sabes como solucionar, cuando se pone la pantalla en negro cuando instalas windows? se actualiza el driver pero la pantalla se pone en negro, imac early 2009
Thank you for the lovely video. A quick question: I assume that the old balls have the same pressure as our atmosphere as you placed them inside the kegs. After you initially set the pressure to 30 PSI, did you have to put more air inside the keg later since the keg's internal pressure was reduced by the increase of pressure inside the balls?
Awesome video man! Quick question though…when pressurizing the chamber, I noticed that I’m hearing and feeling “popping” inside (at around 30 PSI). Are the tennis balls bursting? 😲 The balls are about a year old.

Any one got this to work ? I have the same set up, I tried to pressurize with different pressures (29 to 31 psi) and different durations (1 to 2 weeks), nothing worked ! I also checked the pressure was not leaking during the whole process.
