If a Ziploc® brand bag full of nuts is shaken, which pieces will end up at the top? You might guess that the bigger, heavier pieces sink to the bottom, but that’s not actually what happens! In this experiment, you will see the Brazil nut effect, where larger objects rise above smaller ones. This effect is named after Brazil nuts, which tend to end up at the top of mixed nut cans, but it can happen with all sorts of dry snacks (we’re looking at you, muesli and trail mix). In order to really see the Brazil nut effect in action, let’s experiment with something super small (like rice) and something much larger (like jumbo marbles).
