The internal frame holds the balloon up vertically so, when filled with water, it appears to be inexplicably standing vertically without spilling or tipping over.
Instructions: cut the end (the part that looks like a ring) off the balloon off with scissors. Then stretch over the internal frame (large end first). Once the balloon is stretched over the entire frame, fill with water. (Tip: try to center the bottom of the balloon with the bottom ring of the internal frame.)
