Authentic Ferrofluid Sample in 10ml Vial - Comes With Neodymium Magnet!

Authentic Ferrofluid – 10 ml Glass Vial of Living Liquid Magnetism - Great For Magnetism Demonstrations!

This authentic ferrofluid has midnight-black nanoparticles suspended in carrier oil, ready to explode into impossible liquid spikes the instant a magnet comes near.

Inside the premium 10 ml glass vial you’ll see a perfectly still, black liquid… until you bring a neodymium magnet close. Then it happens: hundreds of razor-sharp spines leap toward the magnet, writhing and dancing like a living alien organism. Move the magnet and the entire sculpture follows, stretching, splitting, and reforming in real time.

Perfect for:

• Jaw-dropping science fair demonstrations
• Mesmerizing desk toy that never gets old
• Photography & macro videography (the spikes look unreal under good light)
• Teaching magnetism, field lines, and surface tension in one hypnotic motion
• Gifting to anyone who still thinks physics is boring

Each vial is filled with carrier oil, sealed, and comes with a strong rare-earth magnet disc so the show starts the second you open the box.

Warning: once you see ferrofluid dance in person, every other science demo will feel flat.

Grab the original liquid magnet before it’s gone, because once people see this in real life, they all want their own!
