The Epic Battle: Flamethrower vs Aerogel

TLDRIn this video, Ben tests the insulating properties of aerogel using a flamethrower. Aerogel, made of silica, has a sponge-like structure that makes it an excellent insulator. The flamethrower is powerful enough to melt chocolate, but the aerogel remains cool to the touch even when exposed to extreme heat. This versatile material is used in various applications, from insulation for oil pipelines to keeping cell phones warm in ski jackets. The battle ends with aerogel emerging as the clear winner.

Key insights

🔥Aerogel, made of silica, has a sponge-like structure with tiny pores, making it an excellent insulator.

❄️Aerogel can withstand extreme temperatures, remaining cool to the touch even when exposed to high heat.

💪Aerogel is used in various applications, including insulating subsea oil pipelines and providing safe touch pockets in ski jackets.

🌍Aerogel is also used in cryogenic applications to keep cold pipes insulated, preventing ice formation and ensuring safety.

💥The flamethrower used in the test broke down due to the intense heat, while the aerogel remained unscathed.

Q&A

What is aerogel made of?

—Aerogel is made of silica, the same material as sand or glass, but with a unique sponge-like structure.

Why is aerogel a good insulator?

—The tiny pores in aerogel prevent hot air from diffusing through and its nanoscale structure inhibits the conduction of heat.

What are some applications of aerogel?

—Aerogel is used as insulation for subsea oil pipelines, in cryogenic applications, and even in ski jackets to keep cell phones warm.

Can aerogel withstand extreme temperatures?

—Yes, aerogel can withstand extreme temperatures, remaining cool to the touch even when exposed to high heat.

What happened to the flamethrower in the test?

—The flamethrower broke down during the test due to the intense heat, while the aerogel remained unscathed.
