Abstract

The lifting effect of an effervescent tablet in the water is ideal for educational purposes, because it combines various mathematical and physical principles. We developed a mathematical toy model for the time evolution of the buoyancy and the weight on such a tablet. According to this model we conclude at a mathematical formula which connects the lifting time of the tablet with the geometrical characteristics of it. We tested this formula experimentally and it seems to be confirmed pretty well, according to the experimental data.
