thing green carden canes
light small foil container to hold burner
IMPORTANT - Talk to cubs about the danger or releasing one of these baloons:
* fire if it comes down on a flammable surface
* injury to animals if they become tangled in it or eat it.
Their balloons will be tethered so they can be easily retrieved.
LIGHTING BALLOONS SHOULD BE DONE BY A LEADER
halve the sticks and make a cross
attach the metal tray to the center of the cross
attache the 4 ends of the sitcks to the openings of the bin bag so it holds it open
attach some string to the crossed sticks and tether other end to the ground
put cotton wool in the metal dish
light and see if it floats.
