Acoustic levitation
It is based on the creation of a standing sound wave in the air capable of keeping particles suspended.

3D Magnetic Field 😎
Even those students familiar with magnetic fields in the two-dimensional plane will be fascinated by this spectacle 😵
Through this cube, we can observe the magnetic field field lines in 3D in a startling new way
Just shake the oil-filled cube, drop the included cylindrical magnet into the center compartment and watch how the iron filings react to the presence of the magnet 🧲

🕺Dancing spiral 🌀
The dancing spiral isn't just nice. It is brimming with science 🔬
😵💫 The mesmerizing movement is caused by impulsive torsion-twisting waves that propagate up and down the length of a series of weighted rods connected by an elastic band that acts like a torsion spring
⚡️This device is both kinetic art and a demonstration of how energy can move through a series of connected harmonic oscillators
🌊 Waves can be generated by a switched on impulse motor or manually initiated to create waves of varying lengths
