The head of a pin is about 2mm in diameter. Use this animation to compare the relative sizes of cells and organisms sitting on a pinhead. Nearly invisible without magnification, dust mites dwarf pollen grains and human cells. In turn, bacteria and viruses are even smaller.se this animation to compare the relative sizes of cells and organisms sitting on a pinhead.

Embrace your inner mathematician and take a look at the numbers: GSM, or Grams per square meter, is one of our favorite cheat sheets for assessing the weight of towels quickly. GSM is simply the measurement for how much cotton is used to make a towel or the density of a particular style of towel. The best part of the GSM numbers is that you can choose a towel based on this measurement. If youâre looking for that solid, high use towel for a crew of kids, 500g will work magic for you. However, if you want that luxury hotel decadence, 800g will be your lucky number.
