Teachers, save “Liquidy Rainbow Inquiry” to assign it to your class.

1.) Add one drop of red food colouring and one drop of blue food colouring to 1/4 cup of honey and stir until combined. This creates a purple colour liquid. Pour the purple liquid carefully into the tall jar. 2.) Add about 1/4 cup of blue dish soap to the tall jar. 3.) Then add a few drops of green food colouring to 1/4 cup of water and mix until combined. Then carefully pour the green liquid into the tall jar. Tip: When pouring in the green liquid, tilt the jar so the liquid runs down the side of the jar slowly. 4.) Wait a few moments and then slowly pour 1/4 cup of oil into the jar. Tip: Again, be very careful when pouring in the liquid. Make sure to tilt the jar and pour very slowly so the colours don’t mix. 5.) Add a few drops of red food colouring to 1/4 cup of rubbing alcohol or peroxide and mix until combined. Then carefully pour the red liquid into the tall jar. Tip: I can’t stress enough how important it is to tilt the jar and pour slow. Otherwise, the colours will mix together and you won’t get a distinct rainbow. Why did it do that?
