This exhibit is a good sample of utilizing traditional entertainment principles on the level of modern technology. Visitors proposed to measure their strength by gripping a joystick for 15 seconds after pushing start button. Set of electronic sensors attached to the joystick allow a pole with lamps dynamically indicate the level of strength of the grip - the stronger the grip, the more and faster lamps lit up. The exhibit is completely modifyable:
informative graphics panels could be attached to it around the pole, or, as a high-techy option, a monitor could be installed to the exhibit. The monitor would graphically indicate how strength of grip dynamically changes over the coarse of 15-second grip.
