Two-pin plug in three pin socket

Use a sharp object (e.g. screwdriver) and insert it into the neutral port (bottom-left). Simultaneously, insert the right pin of your two-pin plug into the live port (bottom-right). Then, remove the sharp object while inserting the left pin of the plug into neutral port as usual.

CAUTION: Do not insert any sharp object into the live port (bottom-right) as you may be electrocuted. Turn off the switch before attempting any of this.

Visit to Science Centre

Brought the 10 winning students to Science Centre where we saw an exploding hydrogen balloon, live electricity, F1 simulators and many more.

Didn't get a thank you though. =[
