Spike RED Colored Ferrofluid in a Bottle Magnetic Liquid Sculpture Educational Display Executive Desk Toy

Recently learned / stumbled upon ferrofluid magnetic liquid. Immediately became obsessed. This stuff is AWESOME! After much research MTR Designs offered some of the coolest displays available. My displays arrived quickly. I did have a small issue, which Matt in customer service resolved RIGHT AWAY! Thanks MTR. Can't wait to hand out the Christmas gifts spreading the obsession.

Bought this for the significant other for Christmas. She wanted an 'executive toy' to entertain her while she worked at her office desk. Upon receipt, the first surprise when opening the box is how small it is (looks much bigger in its advertising).The unit is basically an upside down mini mason jar filled with discolored oil and the ferrous material. The magnet provided is suitably strong but the concave top (bottom) of the mason jar where you can choose to store the magnet is also the most important part of the entire glass dome for attracting the ferrous material to the top and playing around with it. Yes the sides too but the top is where its fun.Summary: Does what its supposed to but the implementation could have been better.

This is a mesmerizing product. Incredible company with customer service being their #1 priority. I would definitely buy in other colors/sizes in the future.
