a few chambers rather than our big balloons. and harold can take under an hour to do. >> how many balloons -- i mean how big are the balloons? >> the balloons are huge. they're up to 60 feet long, and each one of the balloons is bigger, bigger than the heads on mount rushmore. >> that's a good question, very good question, gabriel. >> very good. smart boy. good for you. give me another one. >> any other questions? >> how much helium do you have to put in them to make them this big? >> how much helium? each one of the balloons has to rise, right? so we know that helium is lighter than air. and some of the balloons are actually filled with helium and air because you want them to fly at a certain angle. so since helium rises and air doesn't, sometimes just the front of the balloon is filled with helium and the back is filled with air. and we're the second biggest user of helium in the united states. >> look at that. well, thank you so much. and happy thanksgiving. >> yes.
