Ejection Charge Tests

We have been playing around with various ejection charge systems and material.  Last year, one of our teams used a timer to activate the charge.  The timer was triggered by an accelerometer.  They built the charge device from a small light bulb and crimson powder.  This year we acquired some Pyrodex.  We also figured out how to statically trigger the timer by bypassing the accelerometer

Here is a video of a static test using different amounts of Pyrodex.
