This is the first static test with our homemade tar/oxygen hybrid rocket motor.這是首次靜力試驗，與我們自製的焦油/氧氣混合火箭發動機。 James Turner and myself (Eric Stackpole), and two of our friends, Jeff Bernard and Caleb Lesher did this project last summer because we wanted to learn more about how rocket engines work.詹姆斯特納和我本人（李家祥斯塔克波爾） ，和我們的兩個朋友，傑夫和伯納德， Caleb lesher沒有這個項目，去年夏天，因為我們想了解更多關於如何火箭發動機的工作。 We built the rocket in James’ garage in Humboldt County, CA completely out of parts we got at the local hardware store.我們建立了火箭在詹姆斯的車庫在洪堡縣，鈣完全失控的部分，我們得到在當地硬件商店。 We had previously done a little over 20 tests with polyethylene, but none of them came close to this having much power (note the shaking of the camera when the rocket fires.)我們以前曾做了很少超過20次試驗與聚乙烯，但他們都不來接近，這有大的權力， （注震動的相機時，火箭火災） 。
