The Clicker Leap

That heavy metal ballpoint pen resting near the lamp was calling my name! I sprinted straight down the spine of a thick hardback notebook, hit the edge at full speed, and took a flying leap. Direct hit! Both of my boots slammed squarely onto the tail clicker. Snap! The spring recoiled with a loud clatter and shot the nib out into a pad of yellow sticky notes. The kickback threw me off balance right onto the felt desk mat, but I scrambled up immediately. That mechanism has serious power. I brushed off my knees and lined up to inspect the spring again!
