Fact or Friction?

Color your days with brainy trivia using this yearly calendar, designed with heat-sensitive boxes that keep historic facts at your fingertips.

Simply rub each black box... The heat friction created from rubbing reveals an interesting factoid that happened on that date in history. Laminated for use with dry erase marker(not included). Made in the UK.

Includes 365 facts, for example:
August 12, 1851 Isaac Singer, an American inventor, patents the sewing machine.
December 10, 1901 The First Nobel Prizes are awarded in Stockholm Sweden.
May 22, 1906 The Wright Brothers are granted a Patent for their "Flying Machine."
August 6, 1926 Houdini performs his greatest feat, spending 91 minutes underwater in a sealed tank before escaping.
