✦
Hypnotic shapes on contactBring the magnet close: the ferrofluid rises into spikes, forming valleys, arches, and patterns that seem alive. Each manipulation creates a unique spectacle.
◆
Suspended iron nanoparticlesFerrofluid is composed of iron nanoparticles in colloidal suspension — they follow the magnetic field with fascinating precision and fluidity.
➤
Always different patternsEach manipulation with the magnet creates a different pattern depending on the distance, angle, and speed of approach — the visual possibilities are endless.
✦
Anti-stress & relaxation toolWatching the hypnotic movements of the ferrofluid has an immediate calming effect — a silent and visual anti-stress tool for the office or home.
◆
12 magnets includedDelivered ready to use with two magnets per bottle — immediate use upon opening the package. No additional equipment required.
➤
6 colors — original science giftGreen, Clear, Pink, Yellow, Blue, and Orange brought together in the same set, to line up on a desk or share. Ideal for curious teenagers and adults.
Glass ferrofluid · 7.2 × 2.2 cm · 6-color set · 12 magnets included · iron nanoparticles
Ferrofluid is one of the most counterintuitive materials in existence — a liquid that behaves like a solid when exposed to a magnet. Bring the magnet close to the bottle: the liquid comes alive, rising into irregular spikes and forming deep valleys and structures that seem to defy all logic. Move the magnet away: everything collapses and becomes liquid again. Six glass bottles measuring 7.2 × 2.2 cm, six colors, 12 magnets included (2 per bottle) — fluid physics made visible and contemplative.

For the best visual effects: bring a magnet very slowly closer and watch the spikes (Rosensweig instability) form gradually. Try using two magnets simultaneously on opposite sides of the bottle for more complex patterns. Light the ferrofluid from the side with a small lamp to reveal the depth of the formed structures.
The most fascinating science gift ever: glass, ferrofluid, 7.2 × 2.2 cm, 6-color set, 12 magnets included. An original and memorable gift for a birthday, Christmas, or teacher gift — for teenagers and adults passionate about science and beautiful objects.
Frequently Asked Questions
What does the pack contain?
The MAGNETA set contains 6 glass ferrofluid bottles measuring 7.2 × 2.2 cm, one of each color: Green, Clear, Pink, Yellow, Blue, and Orange. It comes with 12 magnets, 2 per bottle, to animate the ferrofluid right out of the box.
What exactly is ferrofluid?
Ferrofluid is a colloidal liquid composed of iron nanoparticles (magnetite) suspended in a carrier liquid. These nanoparticles, measuring on the nanometer scale, are too small to settle by gravity and remain permanently suspended. When exposed to a magnet, they align and form characteristic structures called "Rosensweig instability" — these regular spikes visible on the surface of the liquid.
Why does ferrofluid form spikes?
The spikes (Rosensweig instability) form when the magnetic force exceeds the surface tension of the liquid. The ferrofluid seeks to follow the magnetic field while minimizing its energy — the balance between these two forces creates the characteristic and regular structures observable on the surface.
Are the provided magnets powerful enough?
Yes — the provided magnets (2 per bottle) are sized to create visual effects through the glass of the bottle. For more intense or longer-distance effects, additional neodymium magnets (sold separately) can amplify the formations.
Is ferrofluid dangerous?
No under normal conditions of use — it is sealed in a glass bottle. Avoid any direct contact with the ferrofluid (it stains and is difficult to clean) and keep it out of reach of young children. Do not open the bottle.
