If there's one proven way to make a rainy day better, it's free beer.
Fullers Brewery is offering drinkers a free pint of London Pride beer every time Twitter users spot rain coming down in the Periscope live stream (which is up and running from 11 a.m. to 11 p.m. daily all month).
They've even got local celebrity weatherman Michael Fish in on the fun.
“I am excited to be part of this campaign, I’ve seen some very rare atmospheric phenomena, but even in all my years as a weatherman, I’ve never seen it rain beer," he told Mashable.
But there is a price for your free beer: You have to follow the @London_Pride account to claim your free pint via direct message—not a big ask for the potential to turn a rainy day right around.
