Large-scale model/orrery of the solar system according to astronomical research current in the 1820s; it was designed and made as a low-tech version for use in academic settings by Joseph C. Hart in New York, NY, 1824.

Here's full answer with explanation 👇
Steel is More Elastic Than Rubber
We generally understand that material is elastic if it can stretch and return to its original shape quickly after being deformed. This is based on the physical properties of matter called elasticity which states that a material will regain its original form after being stretched or distorted. While you might not believe this about steel, physics dictates otherwise. In fact, steel is much more elastic than rubber; this is why it’s used for things like bridges and buildings because when deformed, it recovers quickly and is better than rubber.

Why Do We Study Physics?
Basically our daily life is nothing without Physics. It involves basic fundamental laws of Newton like Law of Inertia, Law of Force and Law of Action and Reaction that define the motion of particles in a drastic manner. Physics tells us about the energy conservation of the universe as well as some other conservation laws. In fact Physics governs our daily life in a better way.

Physicist Lester Hendershot created generators with no visible source of energy and he was immediately accused of quackery.
Lester took the public's reaction into account and by 1960, in addition to two new generators, gave out 56 pages of documentation explaining to humanitarians that the Earth is a giant magnet, which every day can give mankind hundreds of billions of volts.
After the public documentation of the devices, explaining how to use the "power of the Earth" for free and efficiently, a beautiful thing begins: Dr. Hochstetter bought the invention and died suddenly in a train wreck. The only passenger who died during the accident.
A couple of years later, Hendershot is found dead in his house, and it is impossible to say whether it was suicide or something else, because for some reason an investigation into the cause of death was never conducted. In fact, as in the case of other deaths of inventors engaged in the production of free energy.

The Chinese magic mirror
There are no distinctive marks or indentations on the surface of the mirror, but an image appears in the light cast by its reflection. The spot light source here is provided by a mag-lite lamp.

Hand Boiler
It's a bit of experimental glassware, designed to understand the behavior of gas. As you pick up the round part of the glass, the alcohol vapor pushes the liquid alcohol out.
