Danube river race goes green and wacky

These rafts are made from pizza boxes

bike parts, plastic bottles and empty barrels

Location: Harta, Hungary

This year’s Danube river race saw 16 DIY vessels set sail

They could not be made using boats, kayaks or canoes

or any materials that could damage the environment

(SOUNDBITE) (Hungarian) CAPTAIN OF PIZZA BOAT, ATTILA SZOLLOSI, SAYING:

"Our team at the pizzeria is crazy anyway plus we all like the river and we are fans of this village and there are many other reasons why we do this, but the most important one is that we want to have a big laugh."

(SOUNDBITE) (Hungarian) CAPTAIN OF BABEWATCH BOAT, VIKTOR SZOLLOSI, SAYING:"We take part every single year, it is a great way to bring people together. This is the event that we look forward to the most every summer."
