Illuminated Inflatable Bars
When you were a child, you had an inflatable pool.
Now you're an adult, and the wet stuff you want is at least 80 proof - dispensed from your Illuminated Inflatable Bar.
Available in a variety of colours and patterns, it also supports enough weight to be genuinely practical (as it were).
It's also deflatable, of course, so as soon as you're done with it you can pop it in the car and take it with you.
