There were a few raspberries still on the bushes outside and a lonely looking wedge of watermelon in the fridge just asking to whizzed up into this pink drink.  I added a squeeze of lemon to the watermelon and raspberries in the blender and simply whizzed till smooth.  Top up with some fizzy water and its all good.  Of course you could use bought soda water too.
Somebody didn't want to whizz up all the watermelon and kept stealing pieces from the chopping board!! Cheeky monkey.......
