Watermelon

92% water, 100% summer/Food & Drinks

A full-sized watermelon is a surprisingly hefty fruit, tipping the scales at around 9 kg. It's about 92% water by weight, which makes it both a snack and a hydration strategy. Despite being mostly water, it still packs about 1,300 kilojoules of energy, proof that sugar and volume can do a lot of heavy lifting together.
