Kids have to move underneath tables covered in sheets in the dark. Leader has a torch, if they turn torch on whilst they between tables and can identify the person they are out.
4 tables where you can crawl under safely, 4 large sheets to cover each table, torch
Place 4 tables the right way up in each corner of the hut. So that they almost make a circle. Place the sheets over the top of the tables so just the front are covered. They need to be able to get in and out the ends.
They all find a table to go under. They must all go the same way. On go, they que up almost under the tables waiting for their chance to make it round to the next table. If leader catches you with torch light between the tables and ID's them, they are out.
Don't forget its done in the dark.
