    Thank you for viewing the latest revision of the Physics Playground's Jacobs Ladder kit which now uses a 17KV solid state transformer that operates at 40 ma. These will produce a much brighter and safer arc than the traditional NST driven Ladders, not to mention lower ozone and NOx levels, however they must still be used in a very well ventilated area because the ozone and nitrogen oxides are very toxic gases. The latest revised ladder does not have a limited duty cycle and may run continuously unlike the older NST Ladders that heat up. To complete this kit you will only need basic tools and about 1 hour of free time. The instruction document is full of pictures and detailed explanations that will make this a very simple and hassle free building process. In the end, you will have one great Jacob's Ladder that produces awesome bright rising arcs power by a 45ma high frequency ac current.

Dimensions and Specs:

  • 46 inches tall

Thanks for looking!
