'Science GIFs' was one of the largest and most active science-oriented collections on the Google+ social network with over 325,000 followers at the time of its shutting down. This website serves as a backup of the content from the collection.
Electric fields that extend beyond the glass enclosure of the plasma globe are substantial enough to excite the mercury atoms in the fluorescent bulb. The mercury atoms emit ultraviolet light that are then absorbed by a phosphor coating inside bulb that in turn emit visible light.

A cloud chamber is a sealed container containing supersaturated water or alcohol vapor that can be used to detect ionizing radiation. The radioactive gas is an isotope of Radon (Rn-220) that decays into Polonium and then Lead. The v-shaped trails are produced by two alpha particles (Helium-4 nuclei) that are emitted during the two decay events.

Cytotoxic T-cells, also known as Killer T-cells, are T lymphocytes that kill infected, damaged, or cancerous cells in the body. When the T-cell recognizes a specific antigen, it binds to the cell and injects proteins that induce apoptosis (programmed cellular death).

After being struck on the top, the bottle easily moves downwards while the water does not (greater inertia). This results in a near-vacuum forming at the bottom of the bottle (the bubbles) followed by the water collapsing inwards in a process called inertial cavitation. The resulting shockwave causes the glass to shatter.

Since steel wool is so thin, applying a +9V short circuit across it actually results in the metal burning. You can clearly see the burning spread across the surface of the steel wool even after the battery is removed.
