Prove You Have Connecting Tissue

This clear, 6-3/4" X 1-1/8" acrylic tube has aluminum tape at the ends and an oscillator with red, green and blue LEDs inside. You hold the ends and they become a switch with you closing the circuit and starting a little light show. Nice demonstration of conductivity. Powered by non-replaceable coin cell batteries in parallel, but they should last until long after you've lost the device.
