Ok, I sound slightly douche-like in the first post. What I meant was this. I am fully aware that 99% of the "float effect" will be a mental, visual phenomenon. However, I was curious to know if there was an underlying truth to their claim; irrelevant to whether it was noticeable or not. Like I said previously, Jason and I discussed this in quite extensive detail and couldn't conclude with absolute certainty which way it would side.
@juggledave I know what I think... and what I "Think" doesn't really matter.. What I know is that 3 Physics Professors at my university all concluded the same result that I came up with, and I gave them all the specs of the balls... I will not argue with a professor of physics... As you said... " "float effect" will be a mental, visual phenomenon" and nothing more in my opinion.
@Absoluvely nope. I can afford to buy whatever I want. I already have some Gballz. Bought my first set back in 2008 or so. I also use other brands of juggling bags. My favorite balls are my 2.75 inch silicones I bought from Dube. Got about 14 of those. Just saying it like I see it.
This isn't proof, perhaps prove to me they have the same terminal velocity and the same air resistance values and then I might believe you. You are modelling a problem far too much tell the difference between the two. Jason and I, spent about 30 minutes discussing the difficulties with this problem.
@gballz no it isn't. did you throw both balls with the exact same force with the exact same angle from both hands? and you used a russian ball you made your self it seems. the claim was never that "A RUSSIAN BALL" floats. it was that the "NORWIK's", beacuse of their shell and fill is at the peak a little bit longer than a normal beanbag.
@KAGEJOSE Wrong! I talked to 3 physics professors at my university... all 3 agree with me. The difference in weight, distance thrown or dropped, and surface area would need to be extreme to notice a difference. All of them watched this video and agree the 2nd throw is close enough to come up with a conclusion.
@KAGEJOSE I never mentioned anything about a specific brand of Russian ball... as far as physics of a Russian ball compared to a silicone, beanbag, tennis ball, basketball, shit ball... or any other ball, there isn't any difference in the peak time of any of them. By no means is this video an attack on any prop manufacturer.
The shell and sand has nothing to do with the physics of a russian ball. Any shell and any type of sand will produce the same result.... Make a video and prove me wrong!

Russians may not float but their easier to catch.

@juggledave Do your own testing.... make a video and prove me wrong. I have 3 professors that agree with me.
Terminal Velocity... we are talking 3 meters, not 1 kilometer!

@juggledave Also... the peak time.... prove me wrong on there... that is the main concern of this whole issue.

My russians have gforce and float for several seconds xD haha

russians totally float. i use them whenever I try water-skiing while juggling because they float and are easy to spot

@beck232608 I should have said... "Float in the air, the peak time.." The answer is in the video.

The 2nd throw was the most accurate of the height... 2.5"@50g russian and a 3"@140g Gball. The myth is busted!

@gballz still, that was not a Norwik ball. it has everything to do with the fill and the shell.
