Seal and Play

Seal the lid with a sealant i used Blue Rtv. Put a ring around the seal and put on lid. That's all your all done just bring your magnet near the side and watch as the iron oxide turns from a blob to a pokey blob.

How to Make Ferrofluid With Oil

This is another way you can make ferrofluid using oil. First put some motor oil in a cup or dish.

Add the iron oxide. If you want it to keep its shape after you move the magnet away make it thicker than i did.

You can now play with your ferrofluid freely.

CAUTION it is extremely messy and should be treated accordingly.
