Propane is 1.5 times as dense as air, which is why it never understands oxygen's political cartoons in the New Yorker. Sublimate to comedic transcendence with today's Groupon: for $9, you get a 20 lb. propane-tank refill at One Stop Rental – Tool & Party (an $18.13 value, tax included).
One Stop Rental accommodates customers with an invisible stockpile of efficient, clean burning propane. The non-toxic barbecue fuel not only helps to ensure safe outdoor cooking, but also produces less carbon dioxide than traditional grilling methods such as burning charcoal or searing steaks on the engine of a diesel truck. Though not included with today's Groupon, One Stop Rental can also help ignite backyard celebrations with propane grill rental and an assortment of party equipment.
