Rainbow Colored Flame(thrower) Science Experiment!

The video tutorial demonstrates how different metals can change the color of flames when heated. It explains the use of methanol as a fuel to achieve vivid colors and provides step-by-step instructions for creating red, orange, yellow, green, blue, and purple flames using household materials. The tutorial also includes an experiment with a flamethrower and a device that shoots colored fire pillars, highlighting the fun and creative aspects of backyard science.

Why is methanol preferred as a fuel for creating colored flames?

• It is cheaper than other fuels.

• It produces a vivid color without being washed out by orange.

• It is safer to handle than other fuels.

• It is readily available in all households.

Which household item can be used to create a red flame?

• Calcium chloride

• Boric acid

• Table salt

• Lithium from batteries

What color flame does boric acid produce?

• Purple

• Blue

• Green

• Red

Which chemical is used to create a purple flame?

• Lithium

• Calcium chloride

• Potassium chloride

• Sodium

What is a potential risk of using a flamethrower with colored flames?

• It is too expensive to build.

• It could set nearby objects on fire.

• It produces only one color at a time.

• It might not work at all.
