for those of you who didn't know about this. Years ago when I was taking auto shop we used to take an ignition condenser and charge it on a spark plug wire of a running engine. The condenser would absorb and hold the charge from the plug wire and then when someone touched the condenser they would get zapped. We used to drop them into the shop teachers pocket. I don't know if it's against the forum rules to tell you how to do it but it's not really that dangerous. Anyway, hold the condenser just by the wire,hold the body of it to ground and touch a live spark plug wire to the end of the wire coming from the condenser. Be careful not to touch either the metal condenser or the end of the wire coming from it. Just walk up behind some one and touch them with it and see how high they can jump. Just be sure that they don't have a pacemaker because then it won't be funny.

We did the same thing in HVAC school but we used Start Capacitor's and would leave them on the break table. Sometimes the Zap went through their arm's and out their elbows

St Elmo's fire

Its the blue halo you see around powerlines before lighting strikes.
Salors used to see around the ships mast in a thunder storm.

I have seen it around HV switch gear.
once of my fav tricks was to take an aprentice over to a cable end I was making a stress cone for and have him turn out his light when I would high pot the cable ( 50,000 volts ).

The faint glow of St Elmo's fire would be seen if humidity was just right.

SO if you see that faint blue glow around something like a power line watch out lighting is next.....

Watch your P's and Q's was an old English pub saying meaning watch how much you drank. P is for Pints and Q is for Quarts as the way its served.

Leeches can be used to salvage a re-implanted finger if the venous out flow is inadequate. Arterial blood pools in the finger and there is not a way for the venous blood to escape. So your friendly pond raised leech to the rescue. He sucks out the bad blood so the good blood has somewhere to go. Hence, the finger is revascularized. Added benefit the leech's saliva has a anicoagulent in it which helps the blood not coagulate.

If you trying to get a bolt into a hole that you cant reach with you fingers, lay a single piece of electrical tape over the head of the bolt before you put it into the socket/extension and it will keep the bolt in place so you can stab it into the hole.

regardless of what you've seen on cartoons....rubbing two sticks together will not make a fire.....unless one is a match-stick.
just like in the toons no but you can light a fire with 2 sticks . have seen it done a few times on different survival vids . and some of them are millarity trained to survive anything .

Welsh -
A race that is misunderstood by their neighbours the English due to their craftiness and intelligence. The English call the Welsh sheep-shaggers due to an old trick used by the Welsh against their gullible English neighbours in medievel times, when the English had a nasty habit of :censure: sheep. When Wales adopted English law they noticed the penalty for shagging a sheep was less than stealing one (due to the English's habit) so whenever they were caught stealing a sheep they would instead say they were planning to :censure: it instead to avoid the fine.
Therefore there is a very long list of crimes involving Welshmen shagging sheep, although it is only the English who would actually ever :censure: a sheep, it is just another example of the Welsh tricking the English once again.
Englishman "You are going to have your hand chopped off with an axe because you stole a sheep."

Welshman "I was infact taking the sheep to :censure:."

Englishman "Oh, thats good then our law endorses sheep shaggers. You will only have to lose a finger.
