Hypo allergenic. Basically you want dish soap with as few ingredients in it as possible.You can add the baking powder at any step, before or after adding water.

This looks great! You should paint it though for UV protection, even if you're only putting white paint over the white pipe. I worked with someone who did tests on PVC and sunlight, and painted pipe retained 95+% impact resistance after a year in the sun vs ~50% for unpainted.

Nicely done! Glad you enjoyed it!

Metal rings from wire would work. Zip ties are an easy choice

Please use it! And send me a picture of the results. I'm always very happy to see one of my projects used in that way. To electrify it you may be able to slip a piezo pickup in/under the bottlecap, or stick it to the bottom of the bottle.

Thank you very much!

I think it will still work fine.

Yes you could, it would just take a really long time. The result would be very solid though

I've been trying to figure that out. It's not easy with this design. Adding extra fuel either throws off the mixture that causes the explosion to make the vortex in the first place, or burns very quickly and doesn't make a fiery vortex that lasts more than a few inches past the end of the barrel. I've tried both powdered and aerosol fuel to make a fiery vortex ring with so far no success. I'm still trying though, because it would really be awesome to see.

Yes, it's a laser line module. I talk about it toward the end of the video.

Maybe a giant plastic one, but most I've found are made of soft rubber that can't support it's own weight when held from the end.

Yeah I have seen that one, that's a big step up. A little scary using acetylene

Yes, I believe you can wire them in parallel and it will halve the voltage of the 9v battery to each of them. If I am remembering my electronics correctly, you may want to double check this.

The pot should be as narrow enough that when the bismuth fills it it is about as deep as it is wide. Ideally.If you are doing this with your nieces it would be best that they watch from a safe distance. This is not a very good kids project since the metal is extremely hot and may splatter if it contacts water. I have not tried growing the crystals on anything, besides the metal sides of the pot.

Are you using rubbing alcohol instead of drinking alcohol? I haven't tried rubbing alcohol, not sure if that works or not

Probably contaminants in one of the dry ingredients, could be any of the three. Let me know how it goes!

Really nice! Glad it worked well for you

Very cool!

You can try a sanitary tee, it might work. Let me know how it goes!

You can make it as close as you like as long as they're not touching.

Also, no I have not tried soldering with it. It wouldn't be much good for that because high voltage and delicate electronics don't mix.

Around 10 minutes or so of continuous use. It's easy enough to take out the battery when the lighter case is cracked open and add some wires to run it off some other power supply.

I haven't measured the voltage but it's got to be at least 5-10kv judging by how far it will jump. I believe the output is AC.

Cool, I'll take a look.

I'm sure part of the blame for local squirrel obesity does rest squarely on my shoulders...

Paintballs are probably too heavy to go very far.

"Well then that makes a stick welder, a plasma stick welder. An air arc, a plasma air arc cutter. A spray arc, a plasma spray welder. A spot welder, a plasma a plasma spot welder."As far as science is concerned, correct. All of those devices use plasma as their source of heat. If you don't want to call it that due to your workshop experience that's your prerogative.

This is a comment I've had several times due to a misunderstanding of what constitutes plasma. This does not function via the same mechanism as commercially produced plasma cutters, but it does use plasma for the cutting action. Google 'electrical arc' and you will see that every arc is plasma, whether the gas it passes through is inert or not.

The power supply would be the first step.

I haven't, but it's a cool idea.

You're free to end the video at that point. I did not include an ad in the Instructable, what else would you have me do?

Thanks!

It's just marketing. I'm sure they choose that name because they knew it would get them noticed. It's good stuff though.
