Well i was bored and found a switch on the back of my PSU i flicked it a HUGE explosion came out the back of my psu right next to my brothers head scared the hell out of him, and i was left speechless.
Now what i learnt is DO NOT switch you psu yo 115v and plug it into a 240v socket.......
But on that note i can tell you how to make a power point explode!!! (first time i did this i didnt check if the point was off and it blew up in my face....)
1. get some graphite from "pacers/mechanical pencils" you need 3 peices snap one in half so you have two hole ones
2. put the two hole ones in the point but DO NOT Cross them or touch them (uses less lead this way)
3. bridge it with one of the half's
4. stand back and flick the switch on with an out reached arm and turn head to avoid flying anything.....
Have fun use it wisely!!!
****Note*****
If you do cross the two coming out of the point their is a very good chance u will kill the point! so do it my way
If some one does do this show me how it goes over their because of less V's
For more experienced users get one or two of the art pencils that are solid graphite shave done the end with a knife (get parents permission) so it will fit in point now, bridge it with another peice of the graphite. I can almost guarantee that if u do this one you will kill the power point.... BEWARE!!!
If you are worried about the point, use one of the power boxes that schools have, they work nicely.....
Be safe and have fun
