This week we haven’t exactly made any physical progress. When we tested our pipe with the propane running through it it was actually mostly successful.the only true set back was that after we shut off the propane and flames the end I’d the pipe was still on fire. So this week we went to different stores looking for a flame resistant PVC pipe. We have yet to find one but there are still other stores to check.
This week we postponed the fire soundwaves to pursue a different project. We took a potato cannon that was built last year by a previous physics class and rebuilt it as a confetti cannon. We had to redo the entire ignition system because some of the wires had tore. Then we had a test fire and it was successful!
This week as a group we actually made progress. We not only got all the materials together but we also began the construction of our fire tube. We drilled the holes one inch a part and we got the speaker to the point where we can hook it up to an iPod or other music players. This was harder than it sounds because the cord from the speaker had a plug in that didn’t fit in most or any music players so we cut off the plug and stripped the two wires apart and wrapped them around the plug in of a mini to RCA cord and wrapped electrical tape around it to keep it in place.
For our project we’ll be taking a PVC pipe and drill holes about every inch to half inch apart and on one end set up a speaker to send sound waves into the pipe. At the other end we’ll have a propane tank set up to filter propane through the pipe. Once the propane filters all the way through the pipe we’ll set the propane that’s coming out of the holes on fire and watch the fire “dance.” We’re basically setting sound waves on fire.
