Did you use the hole punch to make those holes, or something like a Dremel tool? The can looks like steel rather than aluminum, which I'm thinking would be harder to punch holes in. Do you think your design would work if the candle part was in the bottom of a tall can with the holes punched at the top, rather than the two piece set-up you have? I have a square tea tin I've been wondering if I could make a candle (a.k.a. buddy burner) in the bottom of, taking up only half of the height and punching holes around the top rim. I'm thinking that it would be an all-in-one unit, pot stand and candle, complete with a hinged lid to snuff the light out. Just curious. Haven't tried it yet. Love your videos, and your accent. It's been too many years since I visited Scotland and I long to come back and get out in the Highland and island hills.
Hi Beth, I used a metal hole punch. It gives no blowout like a drill would. The candle makes a good bit of smoke when burning, as long as enough holes are punched and the flame gets O2 it should be fine. I put holes at the bottom and more at the top of the funnel so air can get to it, and quicken candle burn. The lid in the your tin would have to cover the holes you've punched in order to snuff it out. Fire needs 3 things: heat, fuel and air. The way I snuff mine out is with the large can/with lid over the top so it works as a snuffer and a can to put the protoburner in. ps I'm glad you want to revisit Scotland and can understand the accent :).
