Project Goal: Students build and modify a simple trigger-release cork launcher that fires at least 10 feet

Design Variables: Number of rubber bands, length of the launcher, number of combined launchers

Key Concepts

  • Trajectory is the path that an object follows through the air or other fluid
  • Trigger is a device that sets off a mechanism

Prep: Carefully cut corks into quarters (2 per student)

Safety: Always aim cork launchers away from people, even when unloaded.

Step 1: Materials

Please message me to report broken links. All of these materials are used in my other Instructables for kids, so your purchases can be used across multiple projects.

For the basic model, you'll need:
6 craft sticks
3 craft cubes
2 rubberbands
1 clothespin

Synthetic cork
Hot glue
Tape


<p>omigosh. It worked so well. I messed up on step 2 though. I put the second line of popsicle sticks on upside down, so it was left to right. It still worked though.</p><p>thanks!! </p>
<p>Interesting</p>
<p>awsome</p>
Very cool can't wait to make one
<p>i made one and im happy noww ;)</p>
<p>Nice and simple. Great project, man! I've built a launcher for me. A little bit different, but it works too.</p>
<p>great project</p>
<p>made this and it shot like Kobe #greaterthanMJ</p>
<p>hahahahahahaha yah u wish he's not even good. MJ all the way.</p>
<p>you could launch aircraft.cars or boats with this a peg at the bottom of a wood car to ketch the rubber band. place the peg in the front middle and back launch from each to see what the results are. make a glider from a straw and foam for wings or any part you want. Looks like fun.</p>
try using this design just try converting it to a crossbow or trebuchet. but i still love all your projects!:)
Where would you get craft cubes from?
Lance - have you considered modifying/combining this with the Rocket launcher project? With the right modifications this would probably launch the rockets pretty well.
Hey Don, good to hear from you. Yes, I considered this, and I tried shooting straws from these in my class earlier this morning. It does work quite well! But it is a little bit more difficult for the students to use.
Same here...as always Lance makes the engineering connect! I love the connection to Angry Birds. We NEED more educators like Lance!
