Well done Demitri that sounded realy cool.
I did a hallowen show here in the UK (Jack o Lantern not quite so known here, we just call them pumpkins, hehehe)
I started with some PK effects, I had a spoon on the table and I got all the kids to concentrate on the spoon and saying that a ghost was about to come into the room, suddenly the spoon started to lift up on its bowl, then it spun around before falling back into place on the table, (thank you to my M5 for the help there.)
I then took the spoon off the table and spun a yarn about the spoon bveing effected by the ghost (missdirection and a quick switch) and did some Spoon Bending via " Autobend Silverware". They were all gobsmaked when it broke into two pieces and it fell onto the table.
I lightened the atmosphear by doing some sponge ball tricks, like you, I did multiplying balls, vanishes, productions and changes, then there were 4 and ball to square routine. I gave them all a sponge ball as a souviner.
I asked them "who likes magic?" and "who likes money?" then I did a quick coin change form a £1 coin to a 20p piece, with the help on my Raven, that was sweet and they loved it.
I got out a pack of cards, my "Ghost Deck" (well it was Halloween) I started with about 3 card changes, (Erdnase style and a DL) they were very well exepted by the children.
I got the lights in the room turned down by the dimmer switch, and we all sat around in a little circle while they all told a ghost story, after they had finished it was my turn to tell a ghost story, so! off I went telling them all about these 4 happy smiling kings that came from the North, South, East and West and onday some very bad people came and gathered up all the 4 kings and buried them alive!!!!!! (I put them on top of the deck, and did a pass) then I said oneday there was an earthquake and the coffins that had the kings inside came tumbling out of the ground, North, South, East and West, and I asked them what do you think they found when the coffins were opened? and as one child was told to turn the cards over, they found them all to be the "Ghost Skull Kings"!!!!!!!

they loved that story and the fact that the kings were all dead now was fantastic! (a great reaction) That is my way of using the ghost kings from the gaff deck. (feel free to use it if you like it)
I then said lets try somthing different, as there was a PC in the room with an optical mouse, I decided to put my hands into my pocket and grab my RED D'Lights, off we went with the show, I pinched the light from the mouse and proceded to throw it about and pluck it from here and there, it went through my mouth cheeks and my ears, through my tee-shirt etc etc, then I asked who would like to blow out the light, and every kid stood up all at the same time shouting ME ME ME!!!!!!!
There were more quick tricks, but I will not mention them all now or I will be writing an essay.
It was a very fun night and I did a show for about 45 minutes, I got two bookings from that, by some parents for upcoming birthdays.
After all the kids went off to play I did somthing for the adults, in short, Needle Through Arm, Saw (string through neck) Watch Stopping, Wee-Ja Board (from BlackHarts with a change bag and some Tarot cards) Voodoo Ash (a card reveal) and Superman (signed borrowed coin bend)
It was the climax for all of the parents.
Thank you all for listening.
(Maybe I have said too much and this should this be classed as a routine and put into the secret routins section, hehehehe)
