You might know this situation. In the fridge is a delicious chocolate pudding. Before you know it, the whole tasty pudding is gobbled . You should have took more time to enjoy the pudding .
I wanted to make plates, which make you eat less fast.
All four plates should have a different surface texture , which leads more or less to slow and conscious eating.

With this hypothesis in mind, I gave to 40 experimentees one experimental plate and a regular plate. They should just eat two bowls of pudding.
At the end it turned out that the plate with the concentric circles not only make them eat less fast, but also prepares more joy .
