The documentary also revealed that numerous Crown Jewels were buried in a biscuit tin on the grounds of Windsor Castle during World War Two, to protect them from the Nazis - information that was so top-secret, the Queen herself only just found out about it. "Because if you did, your neck would break and it (the crown) would fall off", she said smiling.
"It's not meant for traveling in at all. So there are some disadvantages to crowns, but otherwise they're quite important things".
