Have fun making your own Ferro magnetic fluid in a test tube!

Make it move and create your own cool effects.

A ferrofluid is a wonderous liquid that becomes highly magnetised in the presence of magnets due to its ferromagnetic particles!

When a magnet comes close to the fluid, fascinating black spikes will form as they are drawn out along invisible magnetic field lines.

The movements created by the Ferromagnetic Fluid are mesmirising and look fantastic when on display in your test tube!

How to use:

  1. Take a small amount (1-2cm) of ferromagnetic powder in the test tube.
  2. Fill the tube with water to the top, then seal the lid and shake.
  3. Your test tube will look full of black liquid. Use your magnet to collect the ferrofluid in the water and move the cluster around!
  4. You now have ferrofluid in your test tube!

NOT SUITABLE FOR UNDER 8 YEARS, TO BE USED UNDER ADULT SUPERVISION.

READ ALL INSTRUCTIONS, CAN BE MESSY IF POWDER IS SPILT, MAKE SURE THE LID IS SCREWED ON TIGHT.
