Science Delivered's booths are always interactive. For this year we are thinking a booth with some fun air pressure tricks would be great. There would be a few demo tricks and then two activities guests can participate in. One would be blowing up a large "wind bag" in one breath, the other trying to blow a ball into the mouth of a bottle (close to impossible). But we are flexible, if for any reason there are too many booths doing air pressure we have a bunch of other options.
