Subject: 2 liter bottle launcher safety
Date: Sun, 11 Feb 2001 12:16:24 -0500
What is the maximum pressure you allow your students to use when using
compressed air to launch a 2 liter bottle? What maximum compressed air
pressure can one of these bottles take? Our launcher is homemade, should
we
expect the O-ring seal to limit the maximum pressure? If the bottle were
to
explode will it just split open or will flying fragments be produced? Any
warnings, recommendations, and/or precautions would be greatly appreciated.
