**Title:** Celebrating 1 Million Subscribers with a DIY "Jacob's Ladder" Experiment
**Summary:**
* Creator attempts to celebrate 1 million subscribers by building a "Jacob's Ladder" using a microwave oven transformer to generate high voltage.
* Despite warnings to viewers not to replicate the experiment due to its danger, the creator encounters multiple setbacks, including near-electrocution, melted wires, and a failed capacitor.
* The experiment ultimately fails to produce the desired effect, but the creator finds an alternative way to celebrate using fire, sparklers, and a 3D-printed stand.
* The celebration ends with the creator sustaning third-degree burns due to a structure collapse.
* As a thank you to subscribers, the creator gives away four LulzBot Mini 3D printers to patrons and viewers who comment with a creative need for the printer.
Here are the key facts extracted from the text, keeping each fact as a short sentence and excluding opinions:
1. **Channel Milestone**: The channel has reached one million subscribers.
2. **Celebration Plan**: The creator planned to celebrate by making a "celebration candle" out of a Jacob's Ladder and giving away four LulzBot Mini 3D printers.
3. **Jacob's Ladder Basics**: A Jacob's Ladder uses high voltage, low frequency across two metal rods to create an arc.
4. **Voltage Requirement**: The creator's microwave oven transformer can produce over 2000 volts.
5. **Safety Warning**: The creator warns against attempting high-voltage experiments at home, citing extreme danger.
6. **Arc Creation**: The arc in a Jacob's Ladder starts from the shortest gap and rises due to hot air pushing it up.
7. **Gap Requirement**: For around two kilovolts, an air gap of approximately one millimeter is needed for the arc to jump.
8. **Wire Melting**: Initial wires used melted due to insufficient thickness.
9. **Circuit Modification**: Adding a diode can increase the distance the arcs can jump.
10. **Capacitor Experiment**: Placing a capacitor between the rods was attempted for firework effects but was unsuccessful.
11. **Alternate Celebration Method**: The creator opted for using sparklers for celebration due to high-voltage setup issues.
12. **3D Printer Giveaway Details**:
* Two printers were given to patrons on Patreon.
* Two printers were given to viewers who left comments expressing a need for a 3D printer.
13. **Printer Model**: The 3D printer model given away was the LulzBot Mini.
14. **Creator's Experience**: The creator has used the LulzBot Mini for over a year and is satisfied with its performance.
15. **Safety Outcome**: The creator sustained third-degree burns due to equipment failure and poor setup.
16. **Safety Advice**: The creator advises against attempting such experiments, emphasizing they are not worth the risk.
