Nothing is better in the summer than a water fight - see your adult reading, all chilled on the chair. Go squirt them - trust us they'll love it - just don't tell them we sent you!
Ok plan B - because plan A may not be a great success. Grab some water guns and see out of you and your family and friends can stay the driest. Don't worry if you lose as you secretly win because are garments are not only super soft but machine washable too - so everyone is happy!
