- STRESS RELIEF - It's an advanced toy, to help relief press for adults in the fast-tempo society.
- SCIENCE KIT - It's a good gift for teens to do some science experienments, creative, fun but not boring as normal experiments.
- NOTE - DON'T LEAVE MAGNETS ON THE GLASS. Better leave some gap between the magnets and glass as the ferrofluid is magnetic and responds well to magnets. Ferrofluid bottle should be put VERTICALLY NOT HORIZONTALLY. DON'T buy it where the temperature is below 32℉ OR IT WILL BE BROKEN. WE WON'T TAKE THIS RESPONSIBILITY IF YOU IGNORE IT.

## Customer Reviews

### ⭐⭐⭐ Okay but stains the glass
*by M***R on August 7, 2018*

It was not what I expected so no ones fault but my own. It stained the side of the bottle and would not come off.
