大显身手

1.The original Mangonel was first used in Roman times to fling large rocks at enemies.This Mangonel, though bearing some resemblance to its forebear, is far larger than its Roman counterparts.

投石车可向敌军投掷巨石，于罗马时期古典战争中即已大显手，但中世纪投石车射程远远超过罗马时代的。

2.The Binary Clock, the ultimate gizmo for people who laugh in the face of time, play tiddlywinks on the lap of destiny, and boil bratwurst in the kitchen of fate.

种多能钟，些笑对时间的人们的终极小发明，他们在命运的间隙里闪过的智慧，在宿命的厨房里的大显手。
