I suppose if dad is the brainy type, he wouldn’t really appreciate yet another tie or belt-and-wallet set for the upcoming Father’s Day. Why not get him something useful where he can learn at the same time – the Equal Measure Measuring Cup? This unique measuring cup goes against the grain adding interesting measurements such as the “volume of body cells that die on a good day” or even the “amount of table salt in a large human” to the regular measuring convention of milliliters. You can pick it up from Amazon for $12.45 a pop.
