Equipment: A test tube, A boiling tube, Bunsen Burner, Wooded splint, a bottle of acid, a piece of metal, safety glasses
Method:
1. Light your Bunsen Burner
2. Add your sample of metal to your test tube. Add 2ml of acid
3. Carefully invert the boiling tube above the test tube containing the metal and acid
4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas
5. When you think the tube is full, your lab partner should light a wooden splint
6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Observation:
