Intrusctions:

  1. Gather your equipment
  2. Get the red cabbage and shred them apart
  3. Put the shreded cabbage in the beaker
  4. Put the boilling water in the shreded cabbage.
  5. On one side of the test tube pour 2cm of hydroxide and the pour the other side of the test tube with Hydrochloric acid.
  6. Then use the dropper to suck up the cabbage water
  7. Then drop the tinted water into any tube 
  8. Then try sucking up the acids into different tubes and see what colours you can make!
  9. Some of the colours should be: yellow, dark green, ( or just any green ) purple, blue, pink, or mulitcolour!
