    That's cute.

    I thought it would shock the crap out of someone if they picked it up or something...

    For years I've thought about building a shocking paper weight that activated via a micro switch when lifted off the desk... I wanted to make it look like the Chinese puzzle boxes/Hellrasier box for added effect. I had a small transformer I got out of a desk phone that made some painful shocks from a 9v battery and a 555 timer circuit back in high school. That was the whole high voltage phase... LOL. Best spark I had from a single 9v (so I didn't kill myself) was 1/4" which would turn to an orange arc when you shortened the gap and actually set paper on fire! I used a motor cycle ignition coil.. I started to device a CDI circuit using a HV cap and SCR but never finished it.

    Wow, I started to ramble off topic there...!

          Another fun thing to do is take a capacitor and charge it up (has to be over 40volts as that's the threshold for conducting on skin), take the leads and coil them around the case.

          Then chuck it at someone saying "catch!"

          Ben that's really cool.

              I got nailed by that one a couple of times in my High School days working at the Shell Station part time for a "Buck an Hour" pumping gas!

              Oh MAN do I have stories about those years!

                  I had a coffin box wind up bank that did that. Only you'd lay the coin flat and when you did it pressed a switch and a hand just like that came out and pulled the coin in the casket and as it went in a skull head jumped up and fell back down.

                    Absolutely nerve-wracking to watch too... especially if you decide to take back the coin...

                        That's nothing!

                        Ever take a plug wire off a running 60* coil pack? It will arc about 1.5-2" easily and make you feel like you were hit with a sledge hammer.

                        Best part is if you grab someone else at the same time, they feel like you hit them with a hammer ROFL.

                          I have to build one of those boxes. SO many people at my work would play with it. I have a miniature Craftsman jack (see the 2003? 60V6 pics) on my desk and it never fails, that 50% of people will play with it when they are at my desk. A box with a switch? Oh yeah... I'll post pics when I finish it.

                            My GrandFather would put both hands on the old SparkPlug rods (very old school) and stall it out,
                            My Dads favorite was to grab a hold of a plug wire and ask me for a wrench, soon as I handed it to him, finger in wire and Zap! I would get it. lol
