Review on π¬ Enhance Science Experiments with the TEDCO Sensor Stick Conductivity Energy by Timothy Louis
Just fantastic! suitable for chemical analyzers
I bought a few to demonstrate electricity to sixth graders in science class. It was a great success. We even formed a circle with the students holding hands. Using an energy wand, I asked one student to let go of the other student's hand, interrupting the "flow of energy" and stopping the wand. Fiction!
