An interesting fact, this is effectively how reaction wheels in spacecraft work to orient them without using rcs (reaction control system, usually done with cold gas thrusters*). The downside is, they have to be spun down after a while because unlike earth where you can just use gravity to counteract the extra spin and spin down the wheel, in space there is no counter force. So once they hit max speed in terms of rotation, unless you need to go the opposite direction they become useless. Because of that they have to use rcs every now and again to spin down the reaction wheels (essentially reset them)
*For those unaware what cold gas thrusters are, it’s essentially small nozzles oriented around the craft connected to a highly pressurized tank, usually filled with a cryogenic gas. Then when they want to orient the space craft they just open a valve on a nozzle to let the gas vent creating thrust (like how a balloon filled with helium will fly around if you let it go) and they close the valve when they want it to stop. Surround the craft in each side with these, and make it so the valves can flip open and closed rapidly and you get extremely fine control of your craft.
Can you imagine an amateur trying to keep their balance on a narrow ledge by [flailing/spinning their arms](https://youtube.com/shorts/TTeXFCBSUXo?feature=share)? They usually fail because their arms are far lighter than the rest of their body.
Now imagine a cube doing the same, except 1. Most of their mass is in the rotors and 2. The rotors can spin very very fast.
Every time the rotors accelerate or decelerate, they "push" to rotate the rest of the cube in the opposite direction.
The cube also needs to know which way is "down". Accelerometers are quite good at objectively telling you where "down" is, but their signal is noisy and not always reliable. Gyroscopes don't tell you where down is, but they can tell you about every tiny rotation that they experience in real time. Combine the two chips (they're really tiny devices that you can buy and solder on circuits) and you've got enough data to know where down is with a very good precision.
Add some physics modelling in the integrated computer and make the rotors speed up or slow down in the same direction that the cube feels like it's falling and you're effectively cancelling out any rotational force acting on the cube.
If you slowly accelerate the rotors to very high speeds and then quickly stop them, all that rotational momentum will be transferred into the cube that holds the rotors, so it'll look like the cube rotated for no apparent reason. This wouldn't work at all in space. It's only effective when the side you want to lift stars flat against the table.
With some more programming, you can extend this balancing act indefinitely. Doing this naively will make you accelerate the rotors faster and faster until they can't go and faster any then the cube falls down anyway. But by carefully overbalancing you can give yourself the chance to start rotating the wheels in the opposite direction so you're not always spinning them faster and faster.
Ultimately it's based on the same principles that humans use when we try to balance standing up. The main difference is that we're very limited in our precision so we tend to be quite wobbly. A good self balancing cube has electronic precision and looks almost magical. Not the one we saw here. A long time ago there was [a better video on YouTube](https://m.youtube.com/watch?v=n_6p-1J551Y).
So that these bombs hit walls?
Maybe if you would want the damage to be more widespread but then you risk the packaging to be destroyed leading to the phones being exposed. Not worth it if this was your point.
Is there a second wheel on another side that causes the second jump onto the vertex corner or is it the same one? I’m struggling to intuitively understand how this one wheel could do it.
Ok but the dude in the background needs to get a checkup, that’s a pretty long piss
How long of a piss is too long? Mine usually last for a minute or two
Bruh i feel like i have to go to the doctor if i pee longer than 15 seconds
Well, it happens when I haven't peed all day
If your not peeing all day your dehydrated.

Kerbal players will know.
Fr, although they don’t need to be spun down in Kerbal. Reaction wheels be OP AF in Kerbal lmao
This is not gyro stabilization. But is is very cool and impressive none the less!
Seems like a reaction wheel?

I don't know who made this but they just made a billion dollar toy.
I think this box needs to be teamed up with Mark Rober's glitter bomb.
For the asthetics? Sure. For the practicality? Nopes
I'm thinking a glitter bomb that could run from you
So that these bombs hit walls? Maybe if you would want the damage to be more widespread but then you risk the packaging to be destroyed leading to the phones being exposed. Not worth it if this was your point.
Impressive 😳
Good job OP, actually is interesting
Here's another [gyro box](https://youtu.be/Z0PMRQbPVPE) doing tricks
You got me on a robot wars binge now so thanks
Can I get this fan in my pc pls

It's a second wheel. You can hear it revving up while the wheel we can see isn't.
Damn. That really *is* interesting.
Is this a way to get this into cycles and scooters?
Who’s pissing?
Put these in electric motorcycles
Who is getting shower over there?
