After 30 minutes, one group has drawn bread-shaped clocks and nightlights, and another has designed a “ self-feeding fish tank ” that makes use of a timer. Other students have come up with a set of lute-shaped screwdrivers. And still others make the case that LED lights could be used on umbrellas, vests, or high heels to increase safety while walking at night or during rainy days.
30 分鐘後，這些學生有人畫出麵包造型的時鐘及小夜燈，有人將魚缸結合時鐘，設計出具有計時功能的「自動餵食魚缸」，有人則推出月琴造型的螺絲起子組，也有人認為未來可考慮在雨傘、背心或高跟鞋上加裝可調節燈光的 LED 燈泡，即可提高夜間或雨天行走的安全性。
