firstly you need about 60 cones (the little coloured ones with a hole in the middle, not like a traffic cone). throw these all over the floor in a rough square, it doesnt matter which way round they go, in fact they should be a mix of the right way round and the wrong way round. split the chanichim into 4 teams and give each team a colour. the aim is to turn all of their coloured cones the right way up while stopping the other team turn theirs the right way up (i.e turning them over again). give them a certain amount of time, maybe just a few minutes, 5 max. and at the end they have to stop and which ever team has the most amount of cones thr right way round is the winning team.
