8th Period- Thank you notes to Provost Thomas Sudkamp

List of Demonstrations from the Show

1. Elephant ears- sound vibrations and ear protection
2. Hydrogen balloons
3. Flaming book- fire triangle
4. Breathing Helium
5. Helium vs Hydrogen balloons- pop vs burn/explode
6. Helium vs sulfur hexafluoride gases with organ pipes- or check out Steve Spangler's version.
7. Non-burning rags and colored fire
8. Burning candle and Michael Faraday
9. Physical vs chemical change with wood sticks
10. Dry ice in soap solution [moth balls sublime]
11. CO₂ extinguishes flames
12. Burning Mg wire/ribbon- very bright
13. CO₂ does not put out Mg flame
14. Dry ice sublimes and water vapor cloud
15. CO₂ heavier than air and extinguishes flame
16. CO₂ fire extinguisher & snowflakes
17. Snow Pants
18. Rainbow acid-base indicators (bases)
19. Rainbow bases neutralized with dry ice forming an acid
20. Universal indicator with base neutralized with dry ice and limitation of repetition due to buffer
21. Electric pickle (and colored flame explanation)
22. Silver mirror in flask
23. Liquid nitrogen [LN₂] rapid evaporation
24. LN₂ ivy
25. Elephant toothpaste
26. LN₂ freezes rubber tubing
27. Pillar of fire
28. Jingle Bells
29. LN₂ balloon/stopper pop
30. LN₂ apple & water balloon as a hammer
31. LN₂ and candle flame bimetallic strip
32. LN₂ rubber stopper hammer
33. LN₂ rubber hose freeze
34. Genie in a bottle- decomposition of hydrogen peroxide & cloud formation
35. LN₂ Racquetball failed to shatter this year.
36. LN₂ Hero's engine & Newton's laws
37. LN₂ stopper pop & rocket launch
38. Balloon animals in LN₂- [this year videos & photos]
39. LN₂ Fountain
40. Hand in LN₂ and frozen thumb
41. Whoosh jug with Tesla coil and stopper pop (difference between explosion and fire)
42. Whoosh bottle and slow-burning whoosh bottle (methanol vs 70% isopropanol)
43. Solid-solid cold pack (instant freeze)- I don't have a WSU version of this demo, but I do have one of mine.
44. Conductivity of molten glass & series circuit (molten glass is a semiconductor)
45. Chemiluminesence-chemical glow-stick
46. Persistence of vision and LED "Chemistry"
47. Egg in a bottle (and back out)- air pressure
48. Jell-O^®/Gelatin into a flask
49. Chemical glow-worm
50. Leaky faucet (CO₂ and Propane bubbles)
51. Carbide cannon
52. Colorful Hydrogen balloons- This video is interspersed with another demo they used to close with [sugar torches] that they no longer use because of ventilation issues in the new auditorium.

This is the one they normally do in the spring in place of the Jingle Bells Demo that is my favorite.
