All seeing eye
This eye sees everything!
Warning! Only under adult supervision.
- opaque white plate;
- transparent plate with a hole in the center;
- syringe with glycerol;
- jar with a spout filled with tinted water;
- adhesive pads.
Glue a transparent plate with a hole in the center to an underlay. Use a syringe to squeeze glycerol through the hole, then add some tinted water from a jar with a spout. This creates an eye that sees everything!
The picture is the result of the interaction of two liquids with different viscosities. When glycerol is fed into the hole, it spreads out in a circle – it receives virtually no air resistance. The colored liquid consists of smaller molecules, which, under the pressure created by pressing on the jar of colored liquid, try to push the glycerol molecules apart. At first, they push them apart evenly, but as soon as a gap forms in the rows of glycerol molecules, molecules of colored liquid rush there, pushing each other further and further, forcing their way in like an axe chopping a log.
