Its probobly metal in the air.

I know that ozone smells much fresher.

If you want a little bit more substantial spark, you can use a barbecue grill ignitor. You can buy replacements from a hardware store usually, or get one online. Should be around $5 or so. The sparks can be about 1 inch long if I remember correctly, and are good for making potato cannons.

They all look about the same: long plastic housing, red button with black bezel. It uses the same piezo technology in a butane lighter, only on a bigger scale, and the force required to press the button is a bit more.

Attached is a pic example.

At the school I teach at, the kids like to take these igniters out of lighters etc. They use them to shock their 'friends' in class - great fun!

That's so rude from the kids, you shall teach them not to heart each other.

lol i find that one funny...these little sparkers are harmless....not nearly anything deadly in them

Unles your in a room full of gasoline vapor.

Actually, nothing happens unless the air to gasoline ratio is about 14.5. If the mixture is too rich or is too lean then it won't burn.

Peepsalot · 30th March 2006, 01:33 PM

stoichiometric ratio for air to gasoline is actually 14.7 :wink:

But yeah, 14.5 is definitely close enough.

How your piezo works:

On the right there's a piece of piexo crystal connected to the electrodes.

On the left there's a spring with a pin and a catch mechinism attached to the button.

When you push the button the spring compresses first, then when it's fully depressed the catch releases firing the pin at the piezo crystal and all the mechanical energy is converted into a pulse of electrical energy powerfull enough to ignite gas and even kill some insects but too small to harm you.

Killl a instect? Never tryed that.

Some of the more tough flys take a few zaps before they drop down dead. I doubt it works with some of the bigger insects like cockroaches though, I flyback transtormer will probably zap them but that would smell really nasty.

When it becomes summer I shall Catch some bees (or other flying insect) and freeze them. Then I will bring them back to life with a shock! Although it may kill them in the process...

Most insects die when frozen because ice crystals from in their blood.

Interestingly some insects are active during the winter in the UK despite the fact it can get very cold, I wonder how they cope with it.

That's quite true. I have done that before under controlled conditions. You can actually extinguish a lit match in gasoline, provided you can control the emanating vapors. Liquid gasoline will quench a fire, but the vapors will certainly ignite.
