Getting ketchup out of a bottle can be frustrating. In extreme situations, we might end up embarrassing ourselves as well. A physicist from the University of Melbourne, Dr. Anthony Strickland has come out with a solution for this problem.
He came up with three steps with which you can get some ketchup without making yourself look stupid. The first step is to shake the bottle upwards after ensuring the lid is on. This moves the ketchup particles evenly.
Next, turn the bottle upside down and shake it downwards. Lastly, turn the bottle back up, unscrew the lid and tilt the bottle at a 45-degree angle. In this study, Strickland also suggests that ketchup should not be kept in glass bottles.
