Hi, this is my 1st instructable... I hope this can be useful/funny for you...

The idea is pretty simple... a rubber with a capacitor in it...

How it works:
Step1: Just have to "charge it and trow it"...
Step2: Ask someone to pass you your own rubber...
Step3: LOL

Step 1: What You Need...

Here's a list of what we need:
1->Ancient piece of rubber...
2->A cutter...
3->Something to charge the capacitor...
(maybe some day I'll make another Instructable on this..)
4->A pen...
4.5-->A hammer(optional)...
5->A DrEmEl (simil-dremel in my case)...
5.5-->The most evil dremel bit u can find...
6->Copper wire...
7->A soldering station...
7.33-->Soldering wire...
7.66-->3rd hand(optional)...
8->Hot glue gun...
9->A brain...
10->Nothing else.

Step 2: Cutting...

Simply cut in half the rubber... with a cutter...

Step 3: Marking...

Now we have to know where to use our dremel....

Step 4: Dremeling...

Use a dremel to dig the rubber...

Step 5: Wiring...

Use a soldering iron/station to attach 2 wires to the cap...

Step 6: Where Can I Put the Wires?...

Just follow the following pics...(LOL)

Step 7: Testing...

Test it...

Step 8: Hot Glue Gun...

Glue up the rubb(ish)er...

Step 9: Everything That Has a Beginning Has an End...

This is the end of my 1st instructable...
hope you enjoyed it... Sorry for the possible mistakes...(grammatical's one) but i'm NORTH Italian... you know... in Italy schools are what they are... p.s. have a pranky day...
this will not work. i have tried charging a 6.3v 4700uf cap with a 9v battery and touched the ends and no shock... some help please
your supposed to use a camera circuit to charge it-300 volts not 9
but is there not a chance that if someone had heart problems or somethin and that 300v made there heart jump i think that could kill them
How bad would you feel. haha
It doesn't hurt that bad, but I have a high pain tolerance. It will leave small burn marks, about the size of small freckles.
.....its not volts that will kill you its amps..... capacitors increase voltage and decrease amperage
<strong>not true!!!!</strong>that is a <em>transformer!!!</em>capacitors <em>store</em> charge!!<br/>
oh I get it, it's an eraser! XD
Haha, lol I made that same mistake. I was wondering "Who would ever want to do that?" until i read your post.
What this guy is trying to say is to hide a charged capacitor in a "ERASER" (that's what we call it in North America), and when you pass the eraser to somebody, they will touch the contacts of the capacitor and it will shock them, BADLY. Unless you have some sort of "electrical sensory retardation", it will hurt, but I don't think it will kill you unless you have pacemaker, epilepsy, etc.
Really old people (80+), in my part of North America (Eastern Ontario), sometimes refer to erasers as rubbers. Not sure what names they have for rubber boots or condoms, though.
They would probably call rubber boots "rubber boots" and condoms "condoms"
That would be too easy. I have heard rumour that rubber boots are sometimes called "gumtuckies". Most of the old-timers 'round these parts, probably never heard tell of condoms at all (judging from the family sizes of the previous generation or two); if they had, they'd likely call them "baby-killers".
Haha, now that's funny!
After reading the Instructable I realized that you were talking about rubber erasers, not condoms. You must be British. Life is funny.
I'm North Italian, & I've studied a mix of british & american english in "primary" & "secondary" schools...
In Australia we call an eraser a rubber except those kids who try to heaps funny and go pass you a condom. So although i do call it an eraser to avoid this it's a rubber in australia
I get what it does but i don't get how you charger and dis charge it. Any help?
ok i dont get it what's it do!!!!!
if you charge it it shock someone!
