The Original Vortex Dome Desk Toy - Rheoscopic Fluid kalliroscope Science Toy - Handmade in The UK by David Fowler, Physics Hack

Created by David Fowler of PhysicsHack and proudly made in the UK. The Vortex Dome is a beautiful focus or fidget toy designed for your desk. A vortex lives in here, simply spin the gorgeous glass dome and watch it in action. The stainless steel Vortex Dome is filled with rheoscopic fluid. A mesmerising display when spun, this is a simple but effective desktop distraction. TIP: The magnetic needles can be used to manipulate the fluid in many interesting ways. NOTE: The fluid itself is not magnetic, but there are a few magnetic needles inside the dome which can be manipulated with the magnet provided. IMPORTANT: On rare occasions a coating may appear on the inside of the glass, normally due to the postman holding the parcel upside down. This mica powder is used to produce the effects inside the dome. The fluid is not magnetic, but there are magnetic needles inside which can be moved with the magnet provided, to find them simply spin the dome - they will move to the outer edge where you can then collect with the magnet, and will then form what looks like a brush head beneath the glass. Use them to sweep away the dusting from the inside of the glass... once cleaned this will never come return.
