The Elders tell of a young ball much like you. She bounced three meters in the air. Then she bounced 1.8 meters in the air. Then she bounced four meters in the air. Do I make myself clear?

Have there been any technological advances in bouncy ball technology in the last decade or two?
(lemmy.blahaj.zone)
Mr. Ambassador, our people tell the same story.
We've seen too many body bags and ball sacks!
Bouncy balls are already reasonably efficient. If you want them to be more dangerous, you just get ones that weigh more.
Or make them out of nitrogen triiodide.
Can... can we add shrapnel?
Yes, but only a little and just this once.
Oh, all right. Now, let's talk about the practical applications of Octanitrocubane and the potential to make everything in the vicinity bounce (but not for long).
As a treat
I actually did this research a while back and there is an ultimate bouncy ball that I forgot the name of. I will report here once I find it again.
Edit: Megabounce XTR is the one.
I also have tried the Waboba Moon Ball and that's cool but the craters make it bounce all over the place. Up to you whether or not you want that, but I can't have that unpredictability indoors.
I'm sorry, but the OP asked about boucey balls, not bouncy balls. Nice try though.
Thank you for doing this important research!! I had one with craters when I was a kid! So very dangerous and fun!!
Might’ve been a golf ball
Is ot really that good, the xtr? I just looked it up and am feeling an intense urge to impulse buy
The megabounce xtr says it bounces 85% of its dropped height and its made out of PU foam so it does have durability issues.
The Moon Ball is made out of some kind of hard rubber and that thing will never break on you. You will most likely break things around the house before you ever break the ball.
Most dangerous bouncy ball is a golf ball
Edit: golf not gold
This is a pretty good answer, but my inner child says nah. Golf balls are for adults. I want a bouncy ball!! Or bouncey ball! (depending on your persuasion 😉)
You can carefully crack open a golf ball to reveal a decent bouncy-ball.
From memory, I think it is a weighted core, wrapped in a long thin strand of rubber.
Glue the rubber strand to stop it unravelling and it should be good.
(Crack open carefully means with a vice and a hacksaw, rather than using any knife)
Edit: Turns out the wound rubber strand is only in balls up to 1970, newer balls have solid cores which may be fixed to the outer shell in a way that is hard to extract the bouncy-ball.
Please stop putting in comments about bouncy balls. OP made clear by typing it twice ~~he~~ she wants to know about ~~boucy~~ boucey balls.
1st off she not he.
2nd thank you for the sass about my spelling mistakes! It's especially nice cuz you reversed them yourself lol
Thanks. Fixed it.
*boucey – they're Irish, not Scotch
I see you've got a rye sense of humour.
Since no one is actually answering your question. This was published about 2 weeks ago: https://arxiv.org/abs/2508.18519
An actual scientific article? Love it, thank you!
Check out amorphous metals
Thanks for the video! Those metals are dope!
Makes me want a Saw movie based on weird real life science taken to the extreme. Jigsaw meets Cave Johnson!
Like two people are trapped together in a giant amorphous metal room made to look like a pinball machine. One of the people has to get in a giant amorphous pinball. The other person controls the paddles. If they score enough points in time they both move on to the next room. Well both if the one person isn't splattered inside the pinball.
Sometimes I worry myself slightly
I remember seeing rubber balls about the size of a bocce ball filled to a high pressure with helium. Not enough buoyancy to float, but they definitely took off when you chucked it at the ground
Holy fuck that is amazing! Wanna try one so bad lol
It's not new but there are balls made for bounce juggling that have a 90% bounce ratio

These look like so much fun, thank you!
An outdoor lacrosse ball is super bouncy and has a decent amount of weight. Fun to play with against a wall.
The NBA developed a 3d printed basketball. Does material science count?
The car still flies if anyone is wondering.
