One at school was under the toothbrush cabinet and the other was over where my teacher took the dessert.
Twelve of the pictures were filler items representing the following categories : grapes, hamburger, horse, tree, dinosaur, truck, fork, plane, bike, toothbrush, keys, and fish.
Brushes were stored upright in sterilized plastic toothbrush holders for 1-10 days at room temperature, sampling as above every 2 days.
Both the rock and the toothbrush are looted, in the sense of being taken away, for the purpose of an experiment, from their rightful places.
They carried only two tins of food each and toothbrushes.
The toothbrush seemed to be, literally, just a toothbrush.
He tries to work out when the toothbrush was made, and where it came from (its 'find spot') and he looks for signs of use.
I am armed not with the latest technology but with a toothbrush and a nail.
