I'm offering this creative idea to anyone who wants it, contingent on prior agreement to split the barn bucks 50/50 with me for this fantastic idea.

1) find child with tooth ready to be pulled

2) tie string to said tooth and to door knob

3) have some one else slam door shut

4) at the moment the tooth flies out of said kid's mouth, take high speed image of tooth in mid flight, with doorknob and kid in the periphery.

5) profit
