Once we went fishing with friends for several days. They took with them everything they needed, fishing rods, donks, etc. the tent, and of course the ax. We loaded it all into the car, and drove off.
Upon arrival at the place (in the late afternoon), we set up a camp, set up a tent, built a table, built a fire, prepared gear to start fishing in the morning.
We decided to pump the boat in the evening. We got a boat, a pump, and for business. When you first press the pump, air escaped from the pump itself. They began to look, and a slot in the pump, apparently cut with an ax when they were driving.
What to do, how to build a boat? They began to think, and now one of us comes up with the idea to pump the boat with a car. They started the car, the hose to the exhaust pipe (I had to cut an elastic band under the hose, it is smaller than the pipe). And the boat began to inflate, so quickly.
Now many will ask a question, because the exhaust from the pipe is hot. No, the air exhaust is a little warm. Now we swing the boat only by car, quickly, conveniently. Just in case, they put baby powder in the boat.
Yes, I almost forgot to warm up the car before pumping up. Condensation may fly out of the pipe in the form of water.
Try it and you will like it. Good luck.
