Introduction: Can the Sparks From a Tesla Coil Roast Marshmallows?

Can the sparks from a tesla coil roast marshmallows?

(Cautionary note - we had an expert in the group to help with safety issues).

Step 1: Diagram

First a diagram of what we are building.

Step 2: Winding the Coil

A rig was built to help wind the secondary coil.

Step 3: Top Load

The top load is made out of a wacky noodle and aluminum tape

Step 4: Assembly

We start putting it together.

Step 5: Put in Our Ground

Put in our ground

Step 6: Showtime

Run through our safety steps

Step 7: Roast Marshmallows

Roast marshmallows

I noticed in your diagram that you have all ground paths going to the same ground (NST case, safety gap, strike rail, and the secondary coil are all tied together). I've been looking all over for a clue indicating whether this is a good idea or not. Did you ever ruin your NST or your capacitor? Would you do it differently? Does anyone else think it's a bad idea or have any suggestions? The Tesla Coil I'm working on is very similar to the one above, and I'm afraid to turn it on until I understand the best grounding arrangement. Thanks!

Wait, is that the Tesla coil from the make magazine danger edition? By the way, did the marshmallow roast?

In spite of the voltage being in the 10s of thousands they were only moderately melted. Probably not the most efficient way to cook marshmallows but definitely the most exciting :)

Did you guys happen to take a photo of the marshmallows after? I would love to see that!
