Very cool stuff, mind you don't spill it though!
The fluid comes with two small screwtop plastic containers, along with a standard plastic petri dish and pipette. For the best effect I would advise putting a small amount in the petri dish, barely enough to cover the surface, and approach with a magnet from below. Be very careful, as a strong magnet from the side can easily cause the fluid to fly over the edge out of the petri dish! Be extra careful, since the fluid stains most materials, and can be difficult to wash out. The effect from a magnet is very interesting to look at. The volumes required are very small so this amount could be used to amuse quite a few people.

Don’t recommend
It’s really fun but to to expensive for what your getting and it also is extremely hard to clean I still have stains on my table but if you will buy it please be careful and don’t let it get all over your face like I did.

Not as good as I’d hoped for the price.
Overpriced. As a toy, they do their job.
