An electromagnetic force causes the pods to “float” on air inside a series of steel tubes.

电磁力使吊舱在一系列钢管内的空气中“漂浮”。

So you could see why folks are all pumped up, " gassed up" , " fired up" , " inflated" like " untethered" basket cases who are " floating on air" with their " heads in the clouds" .

所以你们可以看出来为什么人们都很兴奋，加满油，被点燃，充上气，就像没有系绳的篮子一样，脑袋在云端漂浮。
