Things that go boom? Need to present to some kids

I didn't realize that electric hot dog cookers (direct connection to power line) were made in the USA! Unlike the youtube example I did my electrocution a 115VAC not 220/240VAC...

it was meant for 110-120, but BigClive is in the UK

Beware of making small hard things go bang, the bits can travel at extremely high speed and penerate people.

The metal venetian blind in my workshop had one dent from a glass fuse + holder that couldn't withstand the short-curcuit current and another from a transistor in a totem-pole power outout stage that turned on at the same time as its mate during a faulty start-up sequence. By comparison, the fallout from an overloaded electrolytic capacitor is relatively predictable and benign.

Nope. Just airbag detonators. No legal restrictions.

I did the same at 220V 50 Hz :-) I did eat several :-)

Also known as electrician's source.

One problem at least on 220 V is that if the electrode surface might be too small, it might carbonize the sausage around the electrode. Using two metallic forks at the ends help spreading the current more evenly..

Turn off the power. Put one or more 1N4148 or other small signal diode across the wall switch for the lights. Make sure that the switch is on and restore power. Wait for the victim to turn the lights off. Laugh!

Blowing soap bubbles with Oxyhydrogen and ignite them.

I did this as part of an electrical safety demo. I used a 500W lamp in series with a frankfurter using copper plumbing fittings (15mm end stops) to connect. This was on 240V AC.

Switch on and nothing much happens for a few seconds, then the lamp starts to glow presumably as the frankfurter skin insulation breaks down, then the lamp gets brighter and the frankfurter starts to sizzle and cook.

Then you turn it off because no-one wants a conference room smelling like that. Too late, it does. The frankfurter ends are green looking, but it otherwise appears cooked.

I have seen it done with gerkins as a chemistry demo (they don't smell quite so bad). The trick being that by doping them first in strontium nitrate, sodium nitrate or barium nitrate they burn with traffic light colours. It isn't especially safe as live mains experiments go.

Hmmm. Not only cooked, but ionised as well. Nice!
