Review: Funktioniert wie es soll - Alles bestens und gerne wieder ! Review: 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. ## Features - 20ml [0. 67 fl oz] tube. - EFH1 grade Ferro fluid. - Petri dish. - Pipette included. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EZODVX0 | | Best Sellers Rank | #273,184 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #240 in Lab Petri Dishes | | Bottom Shape | Flat | | Brand | FIRST4MAGNETS | | Brand Name | FIRST4MAGNETS | | Capacity | 20 Milliliters | | Customer Reviews | 4.1 out of 5 stars 329 Reviews | | Global Trade Identification Number | 05055641205524 | | Graduation Interval | 20 Milliliters | | Item Weight | 0.03 Kilograms | | Manufacturer | Magnet Expert | | Manufacturer Part Number | F4MFF20S-1 | | Material | Iron | | Material Type | Iron | | Model Number | F4MFF20S-1 | | Shape | Cylindrical | | Unit Count | 1.0 Count | ## Product Details - **Bottom Shape:** Flat - **Brand:** FIRST4MAGNETS - **Capacity:** 20 Milliliters - **Global Trade Identification Number:** 05055641205524 - **Graduation Interval:** 20 Milliliters - **Manufacturer:** Magnet Expert - **Material:** Iron - **Shape:** Cylindrical ## Images ![first4magnets?
