I can’t really tell what most of these are - see if you can. Six second videos demonstrating science fair concepts sponsored by GE
Here’s a rundown. Sorry I haven’t put time markers!
- Collecting water on penny (showing surface tension)
- Simple motor (battery with coil on magnet)
- “Water rise” demo (usually a candle on water dish covered with a glass)
- The food coloring disperses only within the water layer and so it makes for a neat visual effect when the bubbles make their way up.
- ?? [Weird satellite dish / lightning strike animation. Not sure what the point is.]
- Animation of how plants “work”
- Supercooled water freezing
- Static electricity + polarizability of water
- Oobleck
- Classic “volcano” (baking soda + vinegar)
- Vinegar decalcifying an egg shell
- Crystals (likely salt) forming during evaporation of solvent (likely water)
- Food coloring in milk + Q-tip with dish soap on the end
- Potato battery
- Antacid+water reaction powering paper rockets
- Fake snow
- History of flight
- Carbon dioxide formed from yeast feeding on sugar
- “Back to the Future” with LEGO (as science?)
- Lemon juice and baking soda reaction + dish soap for foaming and food coloring for… color; then, lemon juice as invisible ink
- An ad for Burnkit2600?
- Table salt (sodium + chlorine)
- Homage to dinosaurs
- Iron filings on glass surface with magnets beneath
- Tesla coil exciting the gases in a CFL
- A drawing of a circuit? Might be missing the point of this one…
- Not science.
- Not sure what this is. Maybe a frame rate demo of some sort?
- Burning magnesium is my guess.
- Pretending to be electrically shocked.
- Play-doh frog dissection
- Refraction from convex lens made from water glass
- Same idea as the fourth one. I like this one better.
- Food coloring into water
- Hand-drawn animation
- Another hand-drawn animation
- Additivity of light colors via clever illumination and shadowing
- Making zinc sulfide, which glows in the dark
- A short-lived hot air balloon
- Dry ice tricks (in some liquid(?); then making a soap bubble; then vibrating a spoon using the outgoing gas; then in some liquid again(?))
