Just think of it: an umbrella festooned with hydrochromatic ink. It does just what you think, changing its bland white-on-black illustration into a splash of vivid color as soon as it gets wet. And after all, what good is an umbrella unless it gets wet?
Now these gorgeous umbrellas are available in what SquidLondon calls the "Skyline Squidarella Collection," showing the London skyline in monochromatic view, bursting into a cheery rainbow cityscape as soon as you step out into the London fog. Not bad for $35. Check out the video:
