  • This video shows the property of carbon dioxide to go into a supercritical state with increasing temperature. Initially, a small amount of carbon dioxide was soldered in a small glass ampoule at a pressure of about 70 atmospheres. When the ampoule was heated, the carbon dioxide inside began to pass into a supercritical state, thereby creating an unusual state of matter, not liquid and not gas. After cooling, the opposite effect can be observed, quite spectacular. Video by Maxim Bilovitskiy
  • Video of silver micromirrors in solution under optical darkfield microscope demonstrating Brownian motion, Casimir effect and colorful scattering of surface plasmons. Diameter of silver micromirrors range from around 2-20 μm. Thickness of the crystalline mirrors is between 100-200 nm. Video by Siim Pikker
  • Sublimation of iodine under a microscope. The freshly prepared iodine crystals were placed under a microscope, where they started sublimating (i.e. evaporate without becoming liquid) under the influence of the heat of the microscope light. 20x microscope objective was used and bright field contrast. Video by Tavo Romann
  • Melting an iron nail with a supercapacitor. A 3000 F supercapacitor was short-circuited through an iron nail. A current of 1000 amperes caused the iron nail to melt. Video by Tavo Romann
  • Making stainless steel from iron ore by aluminothermy. To better separate the resulting metal from the slag, cryolite and calcium fluoride were added to the mixture. Video by Maxim Bilovitskiy
  • Slow-motion video of a singing male katydid Conocephalus fuscus. Video by Veljo Runnel
  • Jack Dempsey Falling Step Jab in 100 fps slow motion to 65 kg heavy bag and other punches to same and 50 kg heavy bag video analysis supplemented with wrist velocity measurement by accelerometers. Idea of the punch is to have weight on front leg and step forward dropping weight toward ground (Instead back – front leg weight transfer.) and using earth gravity to greatly increase the punch momentum. In essence controlled fall. First punch hits and weight falls on the boxing glove. Video by UncleSamPatriot
