Brief method of experiment:

A burette is filled with the different type of alcohols and you time how long it takes for a ball bearing

to pass through the alcohol. • While doing the experiment don't pour the alcohol in the burette above eye height.

• Were goggles to protect eyes from any spills and slash backs.

• Keep alcohols away from flames because they are flammable.

• Expose of alcohols in a proper waste bin.
