Plastic Forming.mopatin2020-05-31 | Polystyrene is a thermoplastic found in many objects. There are several types mainly because its density is altered inserting gas inside. The less dense is EPS, expanded polystyrene, used in packaging because it absorbs shocks and is a good thermal insulator. Other type a bit less dense is extruded polystyrene, used in food trays and packages. It has less gas bubbles inside. More compact polystyrene can be found in yougurt and drinks cups. The most compact is crystal polystyrene found in CD and DVD boxes, transparent ballpens (bic), boxes, etc.
Music: "Grass", by Silent Partner,from the Youtube Audio LibraryIce Jacking. Incredible Force.mopatin2020-05-18 | When water is frozen into ice, its volume expands with a extreme strength. That force is able to break pipes and even boats. In geology this is called ice jacking and is responsible of a form of rock erosion.
In this video, a plumbing fitting bursts because of the expansion of the ice when water if freezing.
Because of Lenz's Law, the magnetic field of the magnet induces a current in the copper and that current generates a magnetic field that opposes to the first one.

Experiment in a Vacuum Bell Jarmopatin2019-03-29 | Simple experiment inside a vacuum chamber in order to "see" or evidence the vacuum. A PC fan is moving some paper ribbons, when there is no air inside the vacuum chamber there is no particles that the fan cam move, so the paper stripes don't move anymore.
When I open the valve, the air enters the chamber and the ribbons move again.

en.wikipedia.org/wiki/MagnesiumA Black Hole in my TV Setmopatin2019-01-10 | What happens putting a powerful neodimyum magnet close to a cathode ray tube television set?
Cathode rays are electrons in movement inside a vacuum tube. Those electrons, being charges in movement generate a magnetic field so they can be lead to the phosphors of the screen with a set of coils that modulate the TV signal. With a magnet it is possible interact with the electrons and distort the image an alter the colors.

Really Easy to Make.mopatin2016-07-22 | How to make an extremely easy barrier to stop snails from climbing trees. You only need copper tape or easier to get and cheaper, copper wire from an electrical cable.
Wrap the copper wire or strip around the trunk of the tree and the snails will stop at it, not crossing the copper.
Why? It is not clear. Somebody says that it is because of toxicity of copper and other beacuse of an electrolytic reaction that produces a small electric current that disturbs the snail.

How to Make a Heat Engine.mopatin2016-06-21 | A Curie pendulum is a simple heat engine based on the lose of ferromagnetic properties of a material when it reaches the Curie temperature or Curie point.
We have a nickel (Ni) coin hanged from a copper wire so it is attracted to a magnet. A haet source is place below the coin and when it reaches the Curie temperature it is released from the magnet so it swings away from the magnet and cools down, so it gets ferromagnetic properties again and is attracted by the magnet again. And so on.
