Jacob’s Ladder Plasma Tube:
This plasma effect was iconic in the classic Frankenstein movie– but our version is the first to have a brilliant blue plasma discharge, enclosed in an evacuated borosilicate glass tube! Containing a set of “V” shaped wires, a high-voltage arc rises between them, hovering at the top for about ten seconds, and then repeating in a cycle. The speed of its movement is adjustable by a custom power supply, and although the plasma discharge is not interactive to the touch, it is fully sealed within the glass envelope, making the outside of the glass completely safe to touch.
A bright white Jacob’s Ladder is also available.
