Flame jet drill

Have you ever used a straw to blow air and make bubbles in a cup of water? Well, a flame jet drill works kind of like that but instead of blowing air, it shoots out very hot flames!

Imagine you have a big rock that you want to drill a hole in. A regular drill might take a really long time and could even break because the rock is so hard. But with a flame jet drill, the fire can melt and soften the rock so that it's easier to drill.

Here's how it works:

First, a machine pumps a gas (like propane or methane) into a special nozzle. This nozzle is kind of like the end of a straw.

Then, a spark ignites the gas and creates a big, hot flame that shoots out of the nozzle.

The machine moves this flame back and forth over the rock, heating it up until it gets so hot that it starts to melt.

As the rock melts, it also gets softer – kind of like how an ice cube gets softer as it starts to melt.

Finally, the machine uses a regular drill bit to drill a hole in the melted rock.

So that's how a flame jet drill works! It's kind of like using a big, hot fire to make rocks melt so you can drill holes in them.
