Water company Liquid Death is known for its over-the-top marketing — just look at the name. For its latest experiment, it's sticking to its macabre roots with a skateboard deck made with the blood of the greatest skater to ever ride. The Liquid Death x Tony Hawk deck is coated with paint that's been infused with the Birdman's blood. Each one is screen-printed by hand in SoCal and arrives with a certificate of authenticity. Limited to just 100 examples, 100% of the proceeds go to benefit ocean plastic-fighting 5 Gyres and The Skateboard Project, which aims to build skateparks in underserved communities.
