25 MILLION Orbeez in a pool- Do you sink or float?

I was having lunch with some colleagues and we were discussing the extent to which you could drown if you jumped into a

pool

full of water balls. For example, will it reach your leg? Or up to your waist? Or above your heads? Everyone had different theories. In fact, I asked about 100 people and you can see how different the guesses are. So, as a strong advocate of the scientific method, I decided to test our hypotheses. I am here today, in the backyard of the Backyard World. For the past six months, we've been storing these kettlebells in Kevin's yard.

Today the real moment has finally arrived. Well. I am alive! - Okay, ready for this? - Let's do it. Guess in the comments section how far you think we'll

sink

and we'll see if you're right. I think I'm going to

sink

here. Okay, let's go. Oh Lord. This is so crazy. I feel like I'm being squeezed from all sides, but it's so soft and slippery. It seems that I was very wrong and we must refute the false hypothesis. And now that? I decided to call my nephews. Do you want to go swimming at my friend's house?

This is part of my ongoing quest to be the favorite uncle. But I forgot to tell you that it was a

pool

without water. And that Kevin will be there. Are you ready to swim in this? - Well! - Come on, get off! But before we dive into 25

million

balls of water, let's talk about why my hypothesis is wrong. It's all about buoyancy. So here's a conundrum. When this ice melts, will the water level rise or fall? As you can see here, it doesn't change at all. Archimedes taught us that you change your weight in water.

This baseball weighs 135 grams, and when I press it into the water, it will sink until it expels the equivalent of 135 grams of water, at which point it will balance and

float

. Since the water line is in the middle of the baseball, its density is half that of water. That's why Scooby-Doo's quicksand is lies. Because you sink until you displace your weight, and because the density of sand is twice that of a human, half of your body will

float

like a cork. It is impossible for them to drown. Then "Atreyu"... "Atrax"! Relax, your horse will swim. So I will continue sinking into the water balls until I take my weight off the water balls.

Given that she's a little denser than me, and given the packing efficiency of a sphere surrounded by water, about 85 percent of my body drowning makes sense. I thought the friction between the balls would play a role, so I guessed half the distance, so I was wrong. But it's even more fun because the result was unexpected and you learned something. Okay, let's get back to the pool. Get back there! Come on, baby, come on! They do well in this group. Look how happy they are. Well! Oh God! They are here! Guess where my feet are. "Please consider subscribing" Many thanks to Kevin who let us use his group.

He also recorded a video. We performed eight crazy experiments in a pool full of balls. Go watch that video because his clips are amazing as always.
