One problem that can be solved adopting a scientific approach is:
Some time the metal lids on bottles becomes very tight and it doesn't open. We can use the expansive property of metals when heated to solve the problem.
Take some hot water and pour it on the metal lid. It will expand a little and we can rotate it to open the lid.
