Kids mark Pi Day with pie fight

<div class="meta image-caption"><div class="origin-logo origin-image "><span></span></div><span class="caption-text">March 14 is Pi Day, and to commemorate the mathematical constant, the Children&#39;s Museum of Houston closed off a side street in the Museum District and invited 100 children and adults to participate in a shaving cream fight. The battle started precisely at 1:59pm, cleverly paying homage to pi by using its first few numbers, 3.14159. (KTRK Photo&#47; Mena El-Sharkawi)</span></div>
