Safely demonstrate open and closed series circuits without any danger of electric shocks! When the tube is 'turned on,' the red, green, and blue lights light up and it makes an eerie fluttering tone. Activating the tube is the fun part - just touch the metal ends with both hands. Your body forms the conducting material that bridges the gap between the two metal strips and closes the circuit! 7 x 1.5 inches.

This product will support your students' understanding of the Next Generation Science Standards (NGSS), as shown in the table below.
Suggested Science Idea(s)
Students can use the Energy Tube to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria.
A solution needs to tested, and then modified on the basis of the test results in order to improve it.
The Energy Tube can be used to develop and model how two objects interacting through electric fields, illustrates the forces between objects and the changes in energy of the objects due to the interaction.
Energy may take different forms.
Use the Energy Tube to test open and closed circuits or test conductors and insulators.
