My poor minifig's head is stuck in his helmet! Recently I made a LEGO race car with a driver who wore a helmet. Unfortunately, after the race, I tried to take off his helmet and his head came off inside the helmet. Any suggestions about getting it out so he can see again?
You can use some sugar liquid to use as temporary glue to make the head stuck to the torso. Then wait till the sugar is sticky and then try to remove the helmet. Once the helmet is loose you can put the head and torso in warm water to loosen the sugar glue and take it off. Then wash thoroughly to remove remaining sugar.
