The Cap Zappa (£6.99)
Opens bottles, then shoots a spinning bottle cap up to 5 metres.
A solar-powered, fan-equipped cap: the sun shines, a breeze blows, you feel cold, you go in the sun, the breeze blows, you feel cold…
Fool. You are slave to the hat.
Available for ¥1,260 (€12.60)
Easy Open Bottle Cap by Shao-Nung Chen. For those whose fingers have merged to form fleshy clubs and who must now open fizzies with their elbows.
