Re: pic: My POE Ballistic Device Project
Here are some more pictures that might be able to answer some questions some of you might have. I would like some constructive criticism from all you guys. Even though the project is over and I got a 100/100 I want to make it even better. Do any of you see a way of how I could?
PS If you guys have extra time, build one of these things! ITS A BLAST! |

Re: pic: My POE Ballistic Device Project
Was it accurate (distance and side to side)?

Re: pic: My POE Ballistic Device Project
In my physics class we had to make a catapult that shot a hackey sack into a 100 mL beaker from 16ft away and over a 5 foot wall. The wall made it so you couldnt see where you were shooting. Mine was the only one to make it into the cup ^__^

Re: pic: My POE Ballistic Device Project
we had a project in 9th grade where we had varying distances but our materials were limited: only a pencil, spoon, rubberband, paperclip and 1m of tape. the maximum was like 8 feet though. we shot ping pong balls.
my team won ^_^ |

We did eggs. The egg launcher had to weigh less than 1 kg.
I hit 176 feet. Surgical tubing stores energy. Egg lauching energy. |

Re: pic: My POE Ballistic Device Project
So, now that a lot of you have seen the pics....how can I make it better without making HUGE changes? I am adding a coat of paint tomorrow for our presentation so it looks cool!
How can I make it shoot even further for the presentation? |

Re: pic: My POE Ballistic Device Project
I don't know about shooting further, but adding some duct tape will give it that sleeper look that is starting to get in style lately.

Re: pic: My POE Ballistic Device Project
Hey Kyle, That's Cool.
If you don't mind me asking, what exactly was the project? Perry won't have POE until next year and I was kinda interested in what will be going on in that class. |

Re: pic: My POE Ballistic Device Project
Well, in the class you do tons of projects.
-SMET^2 (uses simple machines) -Mouse trap car (self explanatory) -Marble sorter -Ballistic Device -Materials testing -*one more project that I forget...* In the Ballistic Device, we could use anything we wanted to build a machine that would shoot a ping pong ball a to be determined distance between 5 and 15 feet. We had about 5 class periods to build and test, on the 6th day we did some velocity equations, and on the 7th class day we tested. None of the other projects looked like mine. Most were big and bulky that maxed out our 1'x1' footprint. Mine was 5"x11.75". |
