Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Drilling the Holes
Our pipe is two staleness steel pipes 3.5inces in diameter 8 feet long.
Measure out 2m hols every 1.5cm along your pipe, make sure to leave a few inces from both ends of the pipe.
Clean up holes with meetle file.
When drilling such small holes you should poor some wanter on drill bit it makes such a difference.
Step 2: Diaphragm
Cut out large pease of rubber glove to cover end of open side of tube.
Leave one side of tube blocked. When stretching rubber over sends make sure to tape down. The speaker with to put against this side of rubens tube.
Step 3: Gass Connections
We split pipe into 3 drilled 2 large holes between connections. We then welded in gas connections to bottom of pipe and connected using gas fitting and a T junction back to gas bottle.
Reason for having two inlets in pipe was to improve on spread with filling up pipe with gas.
Step 4: Holding Box
Since we where looking to do this outside we built a box around the tube so we can play this ouside, without this the wind blows out most of the flames. We initally used glass front but replaced with 3mm plexy glass to make it lighter.
Step 5: Get It Going
1. Connect the gas
2. Turn it on
3. Let the gass fill up and light gas.
You should see a contant level of light flames along the top. It its not level check level of pipe.
Connect up music and let it play.
