Water Bottle Rocket

For this project, my team and I have decided to make a water bottle rocket.

Materials Used:

• Two 2-liter soda bottles
• Balsa wood
• Duct tape
• Manila folder

Tools Used:

• Bandsaw
• Hacksaw
• Scissors
• Marker

Get all of your materials and make sure they are of high quality. Make sure the soda bottles aren't deformed. Make sure the wood is not chipped or deformed. And make sure the manila folder is not torn.

• Take one of the 2-liter bottles and cut it in half using a hacksaw
• Take the cap side of the half-bottle and attach it to the bottom of the full 2-liter bottle
• Duct tape those two together

• Trace out three of the same fin patterns onto the balsa wood with a marker
• Cut those fins out using a bandsaw

• On the side of the full 2-liter bottle, evenly mark out where the fins are going, near the cap, with a marker
• Attach the fins to those marks with duct tape on each side of the fins and one long piece that goes over for each of the fins

• Make a cone out of the manila folder and use duct tape to hold it together
• Cut out any excess materials from the manila folder as needed
• Reinforce the cone with more duct tape

• Put the cone onto the half-bottle of the rocket body
• Duct tape the nose cone onto the half-bottle side of the rocket using duct tape

You have made a water bottle rocket!
