Sometimes it's just fun to get creative, even if it's not completely necessary. This is one of those times.
The Q YouTube channel posted a video that shows how to put together your own homemade soda machine. This would be especially useful and fun for parties, cookouts and other events where there might be lots of kids running around. It would save the mess, and it would be fun for them to use. That's not to mention how awesome you'd feel being able to brag about your newly found engineering skills.
It may look a little complicated, but nothing you couldn’t do with a little time and elbow grease. Think of all those times the soda bottle was dropped or otherwise spilled when someone was pouring a drink. No more wasted soda! Check out the actual video to see how to make your own soda machine with cardboard, a 9-volt battery, tubes and wires, a button (for using the machine, duh) and an air pump … thing.
Like I said, it's a little complicated at first, but I'm sure you'd get the hang of it. Otherwise, it's also just pretty awesome to watch. Using cardboard like that can allow you to decorate as the occasion determines. Cute little sprinkles and stars for a birthday party? Sure! Pictures of hamburgers and hot dogs for a barbecue? Why not! Adorable.
The process itself starts with someone clumsily pouring orange Fanta all over the counter with his own hand. While this part looks sort of ridiculous, we get the point. Soda is easily spilled when pouring. Maybe not so much by adults … but we get it.
The next step is to take a DC 6V mini air pump motor and snip and trim a wire to thread through one end of it, then twist and secure that sucker. Do this with three little air pumps and then attach the wire to your button/switches. Take another wire and attach it onto the air pumps and connect them to each other, then a 9V battery for power.
Drill two holes into each of your soda caps. Tubes will go through these holes, one from the new soda pump you built, and the other will lead into your glass. This way, when you push the button, soda will flow out of the tube. Then make your box and you're done! Try it out and see if you can get it to work too!
