Powers of Yellow and Rapeseed

Do you know the short film "Powers of Ten" from 1977, in which a fantastic journey along the powers of ten was portrayed in terms of technique? An impressive work for the possibilities at that time, which set a milestone in film technology! And did you happen to wonder why the rapeseed is so beautifully yellow and why we should actually be happy about the yellow dust that spreads everywhere during flowering? The attached video gives the answer :-)
