[@amygreen8297]

A floating helium balloon that is tethered to keep it from touching the interior roof of a closed moving vehicle, in my opinion, is definitely worthwhile experimenting with. The balloon does not have a lot of mass and is much more sensitive to the changing air density that happens when accelerating and decelerating the vehicle (even from turning left, and right too!) Relative to the car, the balloon will go forward when accelerating, backwards when decelerating, and will move toward the inside of a turn when turning.

[@mdtarequzzaman5485]

Plot twist: The car was actually driving by itself while James was poking the butterfly so no accidents happened

[@cry2love]

So basically - the butterfly is pretty lightweight in air, that's why it is almost in the same place when you accelerate or brake, it's kinda like a human in a huge tank of water, but the drone is much weightier than a butterfly, that's why he goes with air that easily. Sorry for my English, I am very Russian

[@ahypixelnon266]

Alex Bird this is really good English for a second language, I thought you were a native speaker until you said you were Russian! :D

Not just the weight, the surface to mass ratio. A small stone the same weight as the butterfly would push through the air like the drone. A piece of paper that weighed the same as the drone would be pushed by the air like the butterfly.

[@jessical9645]

Oh my gosh!! I've literally always wanted someone to do this experiment. Its boggled my mind since I was a child. There was an old car commercial in the 90s where a miniature flock of ducks were flying through the car as it was moving and I was always curious.

[@landsgevaer]

Regarding how the air itself in the car accelerates, that is due to pressure gradients, not so much movement of the air. That also changes the direction of buoyance. Try the same with a fish in a car filled with water to see how that works. ;-) Basically, accelleration or decelleration changes the direction of apparent gravity in your car (equivalence principle), so things start falling diagonally instead of forward, relative to the car. The drone only corrects for the downward fall due to its orientation that it cannot adjust quickly enough; a butterfly doesn't fall as quickly due to its surface area (as pointed out correctly) and on top of that can accelerate very fast itself (they fly in curvy paths) so adjusting to the change is easy.

[@RobertSmith-eb9xu]

[@spriken]

Can we talk about how unsafe this one was! You could have had someone in the passenger seat do the poking or a driver while you did the poking. You can take risks with your own body but bending around to poke a bug while going 40MPH puts other drivers and people/animals on the roadside at risk. I love your stuff but this one could have been done in a safer way.

[@wizzotizzo]

[@_MacGuffin_]

Try a ballon that is attached to the bottom....THAT will blow your mind....

[@Brokendiode]

If you do it with a balloon, due to the surface area of the balloon, and it's mass verses the air in the van, when the break is applied the air in the van will travel to the front of the van, causing the pressure to become higher at the front of the van, which will actually cause the balloon to move backwards and especially if the balloon is a helium-filled balloon, and tethered to the floor of the vehicle. And that is because the atomic weight of helium is less than that of air, you see if you were to take a helium-filled balloon on board the space station, and turn it lose, it would float just like any other object, because of the lack of gravity causing a pressure difference between the floor and the ceiling. What I want to see done is the type 2 superconductor placed on that Trac of 🧲 and placedin a vacuum chamber, with no air to cause frictional losses, as well as add heat to warm up the superconductor, how long will it continue to go around the Trac will it coast to a stop or will the superconductor warm up past the critical temperature and fall off the track????
