Constructing A Pool Float Out Of Red Solo Cups

Because ideas come in all shapes, sizes, and practicality (this one ranks incredibly low in practicality), this is a video of Drew Dirksen testing the pool float he made entirely out of red Solo cups, super glue, and packing tape. Does it float? Yes. Can it support a child? Yes. Can it support an adult with the mind of a child (read: Drew)? Just barely, and not without a lot of cups breaking. So, if you were wondering if you should build your own Solo cup pool float or just buy an inflatable on the way to your next pool party, the answer is clear: invite me to that party or I will crash it out of spite and poop in the shallow end.
