    molten steel is kewl but red hot flint thrown on hard surface looks awesome.. in a jewlery class class room.. in high school.. while stoned (optional). until the girl with new flat open shoes gets "upset", i say sorry, she tells teacher.. etc.. anywho if you try throwing red hot flint down it has wide area of affect. P.s. the affects of throwing red hot flint and molten steel would be awesome at night. INDUCTION HEATER EXPERIMENT REQUESTS: a gyroscope a magnet a magnetic force dual induction a battle of induction an induction circuit? is the opposite of induction affected by induction? might want to be cautious with these.

    Picking up a ruptured (rapidly decompressed) CO2 container without gloves is an insane thing to do, unless you don’t mind destroying your fingers flesh and kind of like amputations of necrotic said fingers. Cylinder would be at dry ice temperatures, as that’s what dry ice is. Decompressed CO2.

    4:38 No. *NEVER* get diet soda or "zero sugar" soda. _WAY_ worse for you than the normal stuff. They substitute a chemical called aspartame instead of sugar (200 times sweeter, which is how it tases the same) and aspartame acts as a neural inhibitor (blocks nerve pathways and signals). While it is "safe" at the levels the government tested it at, it doesn't completely pass through the body and gathers in the liver and kidneys. Which innevitably eventually leads up to a buildup of "unsafe" levels.

    Radiation doesn't always cause a blue glow. Some older clocks and other appliances have small amounts of uranium in visible parts that causes them to glow a similar shade of green to more modern glow-in-the-dark toys. The difference is of course that the older things glow due to the radiation from the uranium (insignificant from such small amounts, unless you eat it, and who eats clocks?) while the modern toys absorb light when exposed to it and re-emit the energy slowly with no harmful radiation at all despite the similar color.
