TSA and baby bottles

Going thru the airport with 3 little ones is never a quick and easy task. Now add baby bottles and ready-made formula to the mix. The agents take the bottles and ready-made formula and inspects them, runs them thru a machine and rubs a "test strip" across them. They rub the "test strip" across the one of the parent's hands and examines the test strips. One parent must go back for another run through the body scanners. If all is well and good you are on your way. All in all, not bad just you feel a little on display.
