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.

<p>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!</p>
Wait, is that the Tesla coil from the make magazine danger edition? By the way, did the marshmallow roast?
<p>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 :)</p>
<p>Well... How well were they roasted!?! The suspense is killing me!! XD Great idea though!</p>
<p>That's awesome. </p>
<p>Did you guys happen to take a photo of the marshmallows after? I would love to see that!</p>
<p>Holy Cow! Now that's one of the coolest experiments I've seen on Instructables....!</p>
<p>That's really cool!</p>
