SGTC Multifunctional Electronics Tesla Coil Module Artificial Lightnings Solid Science Experimental Toy Student Teaching Aids

Features:
Small in size, has a symmetrical and cleans tetragonal structure, the circuits and component are all placed in the outshell.
It has a well-designed circuit system, so that the arc ratio reaches 1.1:1 (the arc length is greater than the secondary coil length).
The arc effect of this SGTC Tesla coil is very cool, it is looks like mini natural lightnigs.
Adopts a novel characteristic fan and space structure for nice heat dissipation effect.
Tesla coil can produce a high frequency and high pressure electromagnetic field, so that the lights that contains conductive-gases can be illumined by the electromagnetic field.
Includes fluorescent light, incandescent, neon light and some rare-gasesglass tubes.
It is a perfect teaching tool to spark students' interest of science, also can be a fine gift.
