If you've only thought of tomatoes as an essential part of a delicious sandwich, you're missing out: they also make excellent projectiles. Since 1945, the world's largest and raddest adult food fight has been fought at La Tomatina in eastern Spain, wherein over 100,000 pounds of tomatoes are annually launched into the faces of revelers in the city of Buñol. Long gone are the cafeteria walls that used to house hallowed food fights of yesteryear; now, partiers strap on goggles and strip down, because it's more fun getting hit by squashed tomatoes when you're basically naked. It's for that reason that Tomatina earned its spot on our list of the 11 Messiest Fests around the world.

Legend has it that, during the 1945 festival of Los Gigantes (a giant paper mâché puppet parade), locals wanted to stage a brawl in order to grab attention. A nearby vegetable cart caught their eye, and they started hurling ripe tomatoes. Innocent onlookers got involved, and the scene escalated into an chaos, with red fruits flying through the air in every direction. Replacing the tomatoes was a small price to pay for the instigators, as it's been 70 years and the party continues to get bigger every year. 

Of course, every good tomato fight's gotta have rules.

1. To avoid injuries, tomatoes have to be squashed before throwing.
2. No other projectiles except tomatoes are allowed.
3. Participants have to give way to the trucks and lorries.
4. T-shirts must be worn throughout the festival (though that doesn’t stop most from ripping them off).
5. No tomatoes can be thrown after the second shot fires.

You can't put on a festival with over 100,000 pounds of tomato projectiles without a little coordination, and the city released the video below with fun behind-the-scenes look from Tomatina load to launch.
