Everyone agrees you need to drink more water but the actual stuff it's self is ,well ,plain. That's when I found Waterdrop. An ingenious little cube in its own packet. Just fill up a water bottle or even better one of their flasks with water and add the cube and wait the seconds it takes to fizz away and you have a drink which has no added sugar and great flavours. Now this isn't my first order and the new flask I got was gorgeous, etched with a leave design it not only looks good but holds 600 MLS of water so you can add your choice of Waterdrop and enjoy. London has started to open the water stations again where you can get free cold water so all you need to do is take a few waterdrops and an empty flask and you are ready to go. Love the idea love the flavours and I highly recommend this idea
