Tech: This cheap homemade liquid changes shapes when near magnets

The creator has called it "ferripaste" and it only costs around £10 to make a kilogram of it.

A YouTube has made his own "ferripaste" at home.

All it takes is black iron oxide to motor oil mixed in a 1 to 1 ratio.

Iron oxide has some of the most magnetic properties that can be found in nature and when mixed with the motor oil, it creates a viscous liquid that reacts strongly to the presence of magnets.

Warning: Do not attempt to make this without the supervision of an expert.

The creator is YouTube channel Brainiac75 and he made several versions of ferrofluid before finding the right mixture. You can find his channel here.
