Tower on the Rug

Wahoo! Clean boots mean it is time to build something brand new! Right on the woven carpet lay four wooden building blocks and a shiny steel ruler. No hesitating around! I grabbed a chunky blue rectangular block with both gloved hands and stood it upright like a sturdy pillar. Next, I balanced a yellow triangle right across the top edge. It wobbled, but I quickly jammed the steel ruler underneath the corner as a counterbalance lever. Clack! Rock solid! One firm tap of my boot proved it wasn't going anywhere!
