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

For the basic model, you'll need:

6 craft sticks
3 craft cubes
2 rubberbands
1 clothespin
Hot glue
Tape

<p>This made my horrible life actually OK. I shoot two people a day with this and since it breaks every time it shoots, I make 3 new ones a day.</p><p>#onelyfethuglyfe</p>
<p>great project</p>
<p>vote 4 trump </p>
<p>vote 4 trump </p>
Very cool can't wait to make one
<p>trump4lyfe</p>
<p>i made one and im happy noww ;)</p>
<p>This was literally the best thing I've ever built in my whole stinkin life. I hate my life.</p><p>#Trump4Lyfe</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>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!
