Globe of Death

A true ringmaster knows any steep wall can become the Globe of Death! I hauled a heavy glass marble over the slick edge of the porcelain bathtub, planted my boots against the slope, and gave it one vicious flick along the ceramic curve. Whirrrr! The little glass sphere tore across the enamel in a blistering spiral, looping faster and faster right above the chrome drain. I threw my arms wide, howling with laughter as the clattering echoes bounced off the tiles. When gravity finally won and swallowed the racer down the plug hole, the whole empty basin rang like a champion's amphitheater!
