does the bottle open?

The bottle is designed to have a minimum torque requirement of 25 ft-lbs to open. That is similar to a jar of pickles or salsa so it can technically be opened by an adult, but is difficult.

Are the magnets included?

Yes! Two magnets with handles are included just like the picture. Thanks!

what is the clear liquid that it is suspended in?

It's a proprietary fluid that makes it so it can work right. Probably not a good idea to drink it, or take the ferrofluid out
