Here is a concise summary of the experiment:
**Experiment:** Dipping Fireworks in Liquid Nitrogen
**Objective:** To observe the effects of liquid nitrogen on fireworks' performance
**Experiments Conducted:**
1. **Smoke Flares:**
* Normal conditions: slow, steady burn with colorful smoke
* Liquid Nitrogen (LN2): fuses extinguished; re-ignition with blowtorch produced thick, condensed smoke
2. **Artillery Shells:**
* Normal conditions: exploded at 80-100 ft
* LN2: reduced explosion height (40-50 ft) with less energetic bursts
3. **10-Shot Aerial:**
* LN2: first aerial shot only 20 ft, landed without exploding (gunpowder too cold)
**Key Observations:**
* Liquid nitrogen significantly slows down fireworks' reactions
* Fuses often extinguished or failed to ignite in LN2
* When re-ignited, smoke was thicker and more condensed
* An unexpected side effect: colored particles from fireworks temporarily colored the liquid nitrogen.
Here are the key facts extracted from the text, each with a number and in short sentence form, excluding opinions:
**Experiment Setup**
1. The experiment involves dipping fireworks in liquid nitrogen to observe their reaction.
2. Three types of fireworks are used: Mammoth smoke grenades, artillery shells, and a 10-shot aerial.
**Smoke Grenades Experiment**
3. Four smoke grenades were lit normally, burning for approximately the same period with colorful, fluffy smoke.
4. The same smoke grenades were then frozen in liquid nitrogen and relit, producing a slower, thicker smoke.
5. Applying heat with a blowtorch was necessary to ignite the frozen grenades.
6. The smoke from the frozen grenades was more condensed than when lit normally.
**Artillery Shells Experiment**
7. A single artillery shell was lit normally, shooting approximately 80-100 feet high before exploding.
8. The same type of shell was then frozen in liquid nitrogen, lit, and achieved only about half the normal height.
9. The frozen shell's explosion was less powerful, described as a "little pop".
**10-Shot Aerial Experiment**
10. The 10-shot aerial was submerged in liquid nitrogen, and upon lighting, only one aerial shot out, reaching about 20 feet high.
11. The aerial landed on the ground without exploding, likely due to being too cold.
12. The gunpowder and stars within the aerial device were still intact after the experiment.
**Miscellaneous**
13. Liquid nitrogen colored the smoke powder, temporarily turning it yellow/orange.
14. The actual liquid nitrogen itself did not retain the color when poured out.
15. The experiment's results will influence a future video on disposing of the unused, frozen fireworks.
