Explanation:
Collect the hydrogen in a submerged test tube.
When the test tube fills with hydrogen, submerge another tube with water and place it over the tubing. You can collect as much hydrogen as is produced by your reaction. Keep the test tubes facing down to prevent the hydrogen gas from escaping into the air.
