1. Prepare a insert into test tube tube experiment
2. Bring the water absorbed from the eyedropper from crushed roses, leading to a drop in both the 6-tube

4. Bring the water absorbed from the eyedropper with the crushed fruits and vegetables to drip into the tube, try steps 2 until all kinds and every tube
5. Shake the tube and apply the Sullivan University paper, the k-value is validated acid. – Bass (pH value) of a color from step 4
6. observe and record the result
