Pro tip: older pennies (before 1932) are solid copper and weigh more. Pennies after then are zinc with a copper coating. Pennies of the year 1932 may be one or the other. This was the year they switched to the cheaper material.
Vast quantities of CO2 could be dangerous for the suffocation risk. highly concentrated CO2 will burn you nose, eyes, and throat if inhaled.
What actually causes the disturbance? is it the coil or the spark gap?
Releasing radiation and releasing radioactivity are two entirely different things. For example light and electromagnetism are forms of radiation. Where radioactivity would refer to the ejection of atoms which decay to release radiation. This rig contains no such capacity
A tesla coil does release electrons.
I've learned a new word, so thank you

Commentary is spot on. Good instructable and very entertaining!
This is a really cool instructable! I am a fan of throwing knives so naturally I had to check it out. Small hiccup, you might want to look at kunai. It's a throwing knife, while a shuriken is a throwing star (aka ninja star). Since these aren't knives, they'd actually be closer to dart, which is how you described throwing them. Hope this helps!
Perhaps by adding additional layers above the grate layer. That would reduce heat loss, just as long as the bellows puts out enough air to sustain the fire by itself. It seems the current design relies on air from above partially. BE AWARE: That adding too many layers could create a stability issue! If you are attempting to melt steel you DO NOT want a hot forge toppling over!! Possibly filled with molten steel!
Those red bricks you are talking about are clay based I believe. You'd probably want solid bricks only, not those newer ones with a decorative side and 3 or 4 holes through the center.
Propane Jet Forge and Anvil Stand
This would make an amazing floor! Replicated as you say, like a quilt across an entire room.
Hey! You just got a new sub! I noticed that you do a lot with concrete and was wondering if you would think about making something for an aquarium? A castle or such? I'd love to hear your ideas!
This is a very sleek design! More appealing than most cobbled together DIY devices. Considered using a wall plug to save on battery cost? (If you'd made a wall plug I would have likely asked about batteries.)
I had a small energizer lizard flashlight that took AAAA. There are also very large cells in a 6v lantern battery (x4). Be sure to get a dry cell (heavy duty not alkaline). I used to take them apart for the scrap zinc and carbon rods.
My only concern is the longevity of using such materials. The oxidation looks okay but after repeated use and potentially rain wouldn't that rust through quickly?
I do something similar but much safer than using gasoline. Use a high proof alcohol and a soda bottle. The soda bottle is thicker and less likely to melt. The alcohol, although it burn hotter, is not as explosive as gas. Pour a small amount into the bottle, shake, and light. DO NOT TIP OVER or you will pour out flaming alcohol. The burning of the alcohol will consume all the oxygen and the only remaining flame will be at the opening of the bottle, blow out to extenguish. Again: keep the bottle upright, never look into it, ensure it is fully extinguished immediatley after each light.
Perhaps tack on a mini instructable of a project for this to be used in?
Very creative! have you played around with making checkerboard patterns (or even a checkers board!) from this? perhaps just make each quarter of a coaster go a different direction to make a swirl? If I had the tools I would definately make some myself!
You have a petroleum product pictured but say to add alcohol. Alcohol if used should be added immediately before lighting due to rapid vaporization.
Glowing Mushroom Wooden Ring
Need I ask the purpose of the alcohol? I understand it is flammable but boiling in hot wax would vaporize it out of the fire starter. Also, have you had any issues striking a wax coated match? Perhaps clogging of the striking strip to where it no longer functions?
Very cool indeed! An alternative to using the box razor is taking apart an old razor used for shaving. The disposable ones are very thin, narrow and extremely sharp. EXERCISE CAUTION IF YOU ATTEMPT IT.
You did not make a speaker you made a speaker box and provided a list of prefabricated materials for a speaker. A heavy magnet reduces vibration. Typical magnets are made of an iron oxide and aren't very strong so they have to be large to produce the desired strength. Smaller rare earth magnets are available for thinner speakers.
