Benham Effect inside – Science meets Play! 🔍🎨
Bring color, motion, and joy to your everyday adventures! Discover two delightful PinWheels—a Large PinWheel and a Small PinWheel—perfect for kids and families of all ages. Both come with a variety of sticks and adapters and an optional mount you can mix and match them freely.
A special strong universal mount fits all PinWheel sticks (Allen key size 8) and attaches securely to strollers, scooter, bikes, handrails, tables, or any rods between 20–45 mm. Just clamp it on and enjoy the breeze!
With scooters or bikes find torch version with one or three small PinWheel sticks.
To keep everything safe and rounded, you’ll also find cover screws and a multi-purpose hook—great for hanging a bag on your stroller.
The Large PinWheel features multiple patterns, including a special 🌀 Benham's Disk design on the backside. As it spins, you and your kids can explore the fascinating illusion of “emerging colors.” Benham was inspired to propagate the Fechner color effect.
