I have a bad habit of spinning caramels.
I bought 4 powerful magnets to work with Hall sensors.
What then thought and one of the magnets was in the mouth... I thought, through the cheek on the outside magnetized the other))) The second pair glued to the other cheek - fun, and magnets round with holes))) Played 5 minutes in front of the mirror in Frankenstein. When I got tired, I removed both the external magnets. How happy were the other two who were left in their mouths between their teeth...
