Benchtop Torsion Testing Machine

Watch metal twist, deform, and suddenly fail! Our benchtop torsion testing machine demonstrates how engineers study material behavior by rotating solid metal samples until they break. Visitors can see real-time measurements of torque and angular displacement as the specimen slowly turns, revealing just how much “twist” metal can withstand before a dramatic pop signals failure. A simple line drawn on the sample transforms into a striking spiral, making the hidden mechanics of torsion visible. This interactive exhibit offers a rare, hands-on look at mechanical testing—and guests are welcome to keep a tested sample as a souvenir.
