7. Tresekundersregeln - LTH:s julkalender 2016

This year's advent calendar is produced by LTH students Ina Rehn Holm, Ingrid Odlén and Hans-Christian Nilsson, who have experimented with a scientific Advent Calendar through 24 short films. Today we go to the root of the myth of the three seconds rule - the rule that says that you can pick up and eat the food that has been dropped on the floor, as long as you do it within 3 seconds. We talk to Åsa and Elisabeth, who work at the Department of Food Technology at LTH, and reflect on how dangerous are the bacteria that you can find on the floor.
