Boys 10th birthday Disco games

[Tiggytico]

Hi. My DS is having a Disco party for his 10th birthday on Sunday.

He's mainly invited boys and I'm now panicking about having 30 10/11 years rioting in a village hall!

What "games" can I organise which would not be too "lame"? I know DS would enjoy anything but some of his friends are probably a little cooler than pass the parcel and musical chairs!!!!

Limbo
Jelly relay: divide players into two teams. Give each team a tablespoon and an empty bowl. At the other end of the room/garden, place a bowl full of jelly. Teams race back and forward to see who can get the most jelly in their bowl within 5 (or 10) minutes.
Shoebox shuffle relay: Teams of about 10. Each team gets 2 shoe boxes. They must race to a cone and back while wearing shoe boxes on their feet. When they return the next person on their team races. They will have to shuffle their feet or they will step out of the boxes. Also if a box is broken that team loses.

Thank you!!
