Science Buddies: "Ask an Expert"

How can you measure air particles using Vaseline? I was wondering how because I had seen a project using Vaseline to measure air particles but it didn't say how, so I was wondering how it measured the air particles.

Hello,

What do you mean by "air particles"? If you mean pollution / particles of solid "stuff" floating in the air, you might want to look at this project idea:

Since vaseline will trap solid particles that touch it, the idea is to measure how much solid "stuff" is floating in the air by seeing how much sticks to the vaseline over a period of time.

After checking out this project idea, let me know if you have any more specific questions.
