Our love of reckless recreation, and our fascination with ‘lost in the wilderness’ movies means that almost all of us could reel off at least a few survival tactics. The trouble is, are they reliable or could some of them actually make...

To get energy for his workout, Tom Thomas needs to cook something healthy without using the stove. He decides to cook oatmeal for the whole family.

Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...
