I’m pretty sure only PP floats in standard corn oil.

I guess I'll resurrect this question marathon,

Hydrogen peroxide and water are very similar, how do you tell them apart?

You shake them a lot and H2O2 bubbles while water doesn't (assuming they're in some sort of separated containers).

This is because water and H2O2 are both colorless, have a near-neutral pH, and are odorless.

Also, you can objectively drink both, but for competition's sake, the first way is probably the easiest.
If life gives you melons, you're dyslexic.

Why can't dinosaurs ski? Because they're dead.

I'm gonna assume you're correct about shaking water and h2o2. But the way I know is you put each liquid in a well, place iodine in each well and stir, then a minute passes and h2o2 *should* bubble while water would be inert besides the color change.

Your turn!

Shaking them is the go-to way to identifying them, so I can confirm jimmy-bond's statement

1. What is the pH of ascorbic acid?

2. A plastic is burned and the flame is green. What is the chemical formula of the plastic?

3. What type of fingerprint has no deltas?

2. I think it's PVC so (C2H3Cl)n

3. I believe arches don't have deltas
