Review: High-quality pharaoh fluid for the best price you’re going to find anywhere. - This is an awesome gift for anyone who enjoys science. I bought this for an experiment which it worked perfectly for, but I have ended up using the extra just to play with. It is incredibly interesting, and educational. All you need is a strong neodymium magnet, and a clear container to put it in. The only issue/problem that I have with it applies to any Ferrofluid, & that is that it is incredibly messy, so you need to either keep it contained, or put down some newspaper, and wear rubber gloves when using it. all things considered, the size of the bottle you get for the price & the overall fun and educational Experience Make it well worth the price.
Review: Good buy - Tons of fun and a good solution for projects.

## Questions & Answers

**Q: The title says 120cc but the description says 30cc which is it???**
A: it is 4oz. So the bottle it comes in is about 3 inches tall and approximately 1-3/4 inches in diameter. hope that helps.

**Q: Can I used it in a magnetic vacuum seal?**
A: The EFH-1 type listed here is not recommended for use in speakers and I would guess that EFH 1 would not have the correct viscosity for use in seals.

**Q: What is the size of the nanoparticles in nm? Can you wash off the oil and resuspend in water?**
A: i don't remember what the size was, although 4 nano meters comes to mind. If you removed the oil and tried to suspend them in water, the particles would oxidize(being exposed to oxygen) and would gather together into redish clumps. All the smooth fluidity would be no more.

**Q: Is this an authentic ferrotec fluid?  what is the model number for it? amgxxx emgxxx etc etc etc**
A: Yes, .. this efh1...  part  number is 92u40000000 / lot number v121021a.. this educational FF.. not for speakers etc
