ELI5: Why is it harder to get glitter off your skin than dirt?
gpt
Glitter is kind of 2D whereas dirt is kind of 3D. As your skin is almost always a tiny bit moist (with sweat and oils) it's harder to get the 2D stuff off than the 3D stuff.

Try this experiment:

1) Lightly spray a concrete floor with water

2) Drop some grapes on the floor

3) Drop some notecards on the floor

When you try to sweep up which is easier?
