Introduction: Baking Soda Powered V6 Engine
In this instructable, I will guide you to create a baking soda powered V6 engine. The engine is powered by 6 syringes, which will serve as the cylinders and pistons. Baking soda and vinegar (or any acid of your choice) will flood the combustion chamber. While this happens the alkaline baking soda will react to the acidic vinegar, causing a chemical reaction resulting in a production of air forcing the piston downward. The power of the other cylinders will force the piston back up, forcing any excess waste through the tanks and out of the engine, then, the same will happening all over again resulting in a circular motion.
Step 1: Gathering Materials and Tools
You will need these supplies and materials to complete this project:
- Drill with phillips drill bit
- Super glue
- measuring tape or ruler (and optional protractor)
- 2 small plastic bins ( 5" by 7" by 1.5" or less, one has to have two compartments)
- 12 gauge aluminum wire
- 6 syringes (10 mL)
- Small eye pins (wide enough for 12 gauge)
- Wood: 2 12" by 8cm by 2cm,2 10.5" by 8cm by 2cm, 1 3' by 1cm by 1cm, 2 3" by 2 cm by 2 cm, 2 5.5 by 1 cm by 1 cm, 2 4" by 3" by 1cm, 2 8" by 7" by 1 cm boards.
- Aquarium airline tubing
- Duct Tape
- Hot glue gun with hot glue sticks
- Baking Soda
Step 2: Building the Base
Cut two 10.5" by 8 cm by 2 cm pieces of wood, and two 12" by 8 cm by 2 cm. Screw together to form a square shaped base.
Step 3: Structure
Cut four 1.5 ft by 1" by 1" pieces of wood and screw onto base 1.5 inches away from sides.
Step 4: Tank Holders
Cut one 7" by 9" piece of wood to fit inside the four beams. Then screw the wood to the inside of the four beams, suspended. Screw the other onto the top of the four beams. Super glue 2 pieces of wood onto sides where cylinders will go.
Step 5: Main Shaft
Bend 12 gauge wire to look like photo:
Step 6: Piston Construction
Drill hole in the bottom of syringe (see photo). Then, thread 12 gauge wire through hole and twist around eyepin. This will give you your cylinder and piston mechanism.
Step 7: Shaft Holders
Drill holes near top of 3" by 4" wood pieces. See picture.
Step 8: Main Shaft
Test to make sure your main shaft (created in step 5), fits into holes and is neither too short nor much too long.
Step 9: Adding Cylinders
Thread main shaft through eye pins on cylinders and glue to beam for cylinders made in step four.
Step 10: Fuel Tank and Combustion Chamber
Drill 3 holes in in sides of combustion chamber (plastic bin #1). Drill two in sides parallel to each other. Drill 4 holes in sides parallel to each other in bin # 2.
Step 11: Tubing
Cut tubes about 6 inches long. Thread into the two holes in combustion chamber and attach other ends to holes in tank. Seal with hot glue. Cut 6 more 6 inch long tubes and thread into three parallel holes and connect to top of syringes.
Step 12: Testing
Pour vinegar into tank in one of the compartments in the top bin, pour baking soda solution in other half of top bin (Baking soda mixed with warm water, half and half). Quickly shut lid of first bin to avoid any escaped air. The two liquids should then flow down the tubing into the combustion chamber (With some air bubbles flowing up the tube to indicate proper sealing.
Step 13: Troubleshooting
If liquid starts pouring pouring out, make sure all connections are air tight. If not seal with hot glue.
If pistons do not move and instead lid pops of combustion chamber, wrap duct tape around to make sure it stays shut.
