MIND-BLOWING PHYSICS MAGICAL TOYS TO MAKE YOU SAY WOW!

Two immiscible liquids of different densities and beads of two different densities. Shake the bottle to mix the liquids, average density of the mix is less than white beads and greater than blue beads. When the liquids separate, both colours of bead are lighter than the bottom liquid but denser than the top liquid.

For the physics quiz, I think there are two types of plastic beads in the jar as well as two types of liquid. Once the beads sink and or float, the liquid then settles to its respective places because one is more dense than the other causing the beads to return to the center dude to the density being different between the two liquids and the two different densities of beads.

The bottle itself says it contains polydensity fluids : ) these two liquids are not so much soluble in each other. So when shaken they form a suspension which is a quite unstable state to be in. The suspension has practically the same density through out. So the difference in the densities of the beads did its job, sending the lighter white beads to the top and the heavier blue beads to the bottom. After a few moments, the suspension dismantles, seperating the two liquids. The white beads are so chosen that it's density is greater than the lighter liquid but heavier than the denser liquid. So it comes down to the interphase of the two liquids. And vice-versa for the blue beads. So, both of them meet eachother to the interphase. I liked the log-algorithmic gears. I wonder where they are used.

Oh hey that last one I had in my chemistry teachers class last year. There’s water and alcohol so the two different densities make a barrier and the two beads are different enough that they also separate out. Thanks Ms. Rathsack!

I know this one! I was thinking about it and here's the science: there are two know kinds of beads with different densities (the blue is greater, the white is less) and clear liquids with different densities too. When you shake, all 4 materials are mixed, and the beads separate first because they are very buoyant and non-buoyant compared to the clear liquid mix. After time, though, the two liquids slowly separate and filter through the layers of beads to the top and bottom of the bottle.

Glad you're still having fun with our spiral gears!

First there were Two bead tribes, The Blue Bison and the White Cranes, living along side the border of their respective Territories. But one day a Catastrophic earth quake mixed them all and they went further inside the territories for survival. As the dust settled and tribesmen returned to their kin, they realised that the territorial border has been left unguarded and the other side can take advantage and capture the fields. So both the sides gathered a militia and charged toward the Border. That;s the untainted truth behind this experiment.

Just found your channel. Love this. I've been fascinated with general physics since I was 10 and learned how to boil water in a paper cup. I've done the surface tension experiment with a tumbler and paperclips. Over 100 before a drop overflow.

I'm going to guess that the liquid in the bottle comprises two different clear fluids, one more dense than the beads and the other less dense. When the bottle is shaken, the liquids mix and the density of the mixture is between the density of the two types of beads so it goes to the middle. As the liquids separate they move to the top and bottom, based on density, pushing the beads back to the middle.

that scale solarsystem looked incredible. im not into astronomy and I can still appreciate the beauty of it.

there are two types of liquids in the bottle that cannot mixed like water and oil but totally same color, different density. the plastic densities are close to each other and between those liquids' densities. that liquids cannot be water and alcohol since because alcohol dissolves in water. it maybe gliserin and water

cool the non circular gear set are 2 Fibonacci spirals meshing together

The answer is The white beads are lighter than the blue beads and they have a magnet inside them so they pulled tho middle

You may not be first...BUT you could be next!

They should have these toys in school. It'd be amazing!!

About the poly density puzzle my solution is the the white ones are made from a different material which the mass of them is lower so they can float and for the blue ones the mass is bigger and they go to the bottom of the bottle you can try it with oil the oil goes up and the water down because of the different mass

There are 2 different liquids added, One liquid is more dense than the other. And so are the beads. (For example and visual lessons), Let's say one of the 2 liquids sits at 1 on a number scale from 1-10, and the other at 10. Add the 2 beads that are 2 different densities and place them at 5. And there you have it. The poly density puzzle answer.

For the puzzle: there are two clear identical looking liquids in the bottle. The order of densities in the bottle goes, from least dense to most dense, liquid 1, white beads, blue beads, and liquid 2. When you shake the bottle, the 2 liquids are mixed, making a liquid with an in-between density that is more dense than the white beads but less dense than the blue beads, and after a few seconds, the 2 liquids separate, and everything goes back to their original order.
