After this risky stunt, you can bet this guy was feeling the highest of highs.

Andy Lewis recently made history when he walked roughly 40 feet between hot air balloons on a slackline 4,000 feet in the air over the desert near Las Vegas. That's about 1,000 feet better than the previous record.

Lewis is a true daredevil -- maybe he could swap stories with these guys to see who's tougher.
