The Backyard Scientist attempted to create a cotton candy gun using various methods, including the Venturi effect, hot air, and a rocket engine. However, these methods failed due to the sugar freezing in the nozzles or burning inside the tube. During his experimentation, he accidentally discovered that pouring molten sugar into a stream of air can create perfect strands of cotton candy. With the help of Mark Rober's assistant, Allen Pan, he successfully created cotton candy using a leaf blower and a pasta strainer. Later, he created a nozzle that can produce multiple streams of sugar, making it easier to create cotton candy.
Here are the key facts extracted from the text:
1. The video is sponsored by Surfshark VPN.
2. The creator of the video, "Backyard Scientist," is trying to make a cotton candy gun.
3. The creator uses a Venturi nozzle to demonstrate the concept of suction.
4. The creator attempts to use the Venturi nozzle to suck up molten sugar, but it freezes in the tube.
5. The creator's next idea is to use a bigger ceramic tube and a wider nozzle.
6. The creator builds a "sugar flame thrower" using an air gun and a compressor.
7. The creator tries to use the sugar flame thrower to melt the sugar and create cotton candy, but it doesn't work as planned.
8. The creator visits a county fair and sees a CNC cotton candy machine that uses a robot arm and tools to make different shapes of cotton candy.
9. The creator tries to make cotton candy by pouring molten sugar into a stream of air, and it works.
10. The creator uses a laser welder to make a special nozzle to create multiple streams of sugar.
11. The creator promotes Surfshark VPN and offers a discount code for viewers.
12. The creator builds a device that pressurizes molten sugar with compressed air and creates a giant cloud of cotton candy.
13. The creator preheats the tank and nozzle in the oven before filling it with molten sugar.
14. The creator adds a nozzle to the end of the device, but it sprays molten sugar back at him.
15. The creator tries different nozzle designs, temperatures, pressures, and sugars, but none work as well as simply pouring molten sugar into a stream of air.
16. The creator tries making a cotton candy machine out of an angle grinder and a fire extinguisher, but it doesn't work.
17. The creator concludes that simply pouring molten sugar into a stream of air is the best way to make cotton candy.
