Remember that panicked moment when your phone almost slipped into the tub while you wallowed along to Sgt. Pepper? No more. Meet Zeppy, a floating wireless speaker which does a whole lot more than make noise. See, Zeppy (€79, Indiegogo) uses a flat panel membrane to propel its waves through the, erm, waves - which means a proper pool party that'll get the lilos going. When you’re not splashing around, it can also be used as a massage aid, because there’s nothing as soothing as Enya for your deep tissue. Got some pals? Pair up to 8 Zeppys for a party that the whole house can feel.
