Be Amazing Toys Energy Stick

Product Information

Simply hold one end of the energy stick and get a friend to hold the other - when you touch hands, the stick will light up and make a noise! There will be activities both indoors and outdoors and the little LEDs just don't pack enough punch in some conditions but I see your point. Is the board needed for the thing to work at all, or can the LED light up if the board is removed and the output wires tied directly to the battery? Sometimes it can be confusing for Non-native English speakers when talking about open circuits, closed circuits, short circuits, on/off etc especially when children use "on" and "open" to mean the same thing in their own language. The Energy Stick features electrodes on each end and when they are touched simultaneously to complete the circuit, long-lasting LED lights inside the tube flash and the tube makes amazing buzzing noises.

A handy little gadget, ideal for teaching basic circuits in KS1, where you can introduce the idea of how a switch works. My theory behind what I think the operation should be is that when there is a very slight flow of current through the circuit (of children holding hands) it is sufficient to turn the 2N2222 BJT on and then the LED.I suggest first supplying the high voltage output from another battery rather than the step up regulator to test if my theory is correct. I have a tiny Al heatsink I can use for the LED but it will be enclosed in a pretty small space so I imagine it will only help for a few moments. So for whatever reason (so long as it in original packaging and perfect condition) simply send it back to us and we'll cheerfully refund you every penny. I used to show a van de graph gen, with the kids hair standing on end, till one kid went home and tried it on the mains . org,which contains comprehensive information on how to do this on a wide variety of desktop browsers.

The old circuit has the potential of destroying the transistors if the resistance between the two ends is quite low as the input transistor will be close to saturation shorting the 3. It’s my job to help with concentration and keeping you on the ball, allowing your brain to work with 100% clarity.You can use the instantaneous response of the energy stick to discuss how the energy must already be present in the parts of the circuit (including themselves! The original works nicely and is exceptionally sensitive but won't turn on when holding only one end. Put a hand on each of the foil ends of the Stick and the flashing lights and buzzing let you know that you’ve completed the circuit.
