4:43 The ball be like:
*Aight. Imma "disconnect" from the game.*

So, for the science behind why a full ball bounces and a half-full ball doesn’t: water is incompressible. When you drop the half-full ball, all of the energy of the collision passes through the water, like a shockwave. It hits the air, which is very compressible, and that absorbs the energy and compresses nearly instantly. With the full ball, the energy has nowhere to dissipate (except for its brief moment of contact with the wooden table), and so the energy of the impact returns into the full ball, causing it to move in a different direction, or bounce. The only reason a ball filled with air (the normal ping-pong ball) can bounce is because the rigid plastic shape takes the brunt of the returned energy. That’s why bouncy balls are filled, with a hardened gelatin, to retain most of their energy. The water-filled ball is genuinely closer to a bouncy ball. It’s also the reason that a normal ping-pong ball will dent on a very hard impact, absorbing the energy, and stopping any bounce.

Which brings me to my challenge idea (if you guys haven’t done it already, just found this channel): Play with a heavily dented ball, multiple dents. That should mess with bounce angles, and make for very interesting post-bounce mental corrections on its projected trajectory.

Edit: I was right, went looking for it, found it from ten months ago. Now I have a playlist to catch up on before my next suggestion. Have a sub :)

"Could be but no."
Ball- You underestimate my power.

3:36 I appreciate that the suggestion is from 2 years ago and they still did it haha

Challenge: play with a ping pong ball full of helium.

[Vishnu_]

Challenge: play with a glass full of water (almost) in other hand. The one who Spill it loses the point

4:52 You should fill the ball only 80% water so the hull remains (mostly) intact during the freezing and then you can play with the ball filled with ice, not only the ice

[kylejensen]

Challenge: Play table tennis with EXTRA long handles.

[Adam-kfdj]

Play table tennis while wearing goggles that turn everything upside down

Half filling spheres with liquids causes maximum sloshing due to the amount of water and free space being equal, giving the maximum amount of water being given space to move. When liquids that flow like water get transported the rule is to either have things full or empty, to avoid sloshing.

Challenge: Play table tennis on an air hockey table!

[megalordx]

This is such an entertaining channel to watch, always finding intresting ways to play the game, awesome

[CMShuckle]

Its reassuring to know that Big Otto could be in a full body cast and still destroy me at the game.

[alvarog]

I laughed loud in front of my parents when you cracked the ice ball and they looked at me as if I was crazy 😂

[Storms]

1:33 "Where did you get this thing?"
Miikka: _We'll get to that later_

[WeebClipper]

Didn’t really knew there was a whole channel dedicated to ping pong

[itsjunny]

When pongfinity uploads, it makes my day better

[ranadipsaha]

3:34 "So we are gonna put one of these in the freezer"
You mean you'll just the leave ball outside for a day.

[qwerification]

What about a frozen ball without removing the original ball? It should ensure a little bit more.
And you may try to fill the ball to 90% before freezing, to compensate the expansion.

Can't believe that they actually make money from the things they truly enjoy doing, I wanna be like them when I get older !♡♡
