In the instructions it says you have to be able to have room for a temperature probe and to spoon to stir the water after the 20 mins. Can we cover the top, but leave space for the temperature probe?
Solar cookers must have an access point to the water that is EASILY accessible for the judge to stir and measure the water at the end of the 20 minutes. How you make this access point is up to you (points for creativity) but there must be room to stir the water and take a temperature reading at the end of the 20 minute period. The access point may be covered during the 20 minute timed period if desired but the cover must be able to be removed very quickly and safely (safety glasses and oven mitts must be worn) at time of measuring. A team member may remove the access point cover without points deducted from the score because it is outside the timed 20 minute period. Teams cannot touch their solar cooker during the timed 20 minute challenge (if it needs to be touched points will be deducted from your score). You may cover the rest of the top of the solar cooker during the 20 minute competition provided that the lamp is exposed to the outside air (refer to lamp questions on blog for more details).
