Science teacher Jacob Strickling created a "strawberry milkshake" using water, red food colouring, cornflour and dry ice.

In the footage he adds cornflour to water producing a non-newtonian fluid which is liquid like when poured, but behaves as a solid when punched.

This mixture is then added to a glass containing some dry ice, the warmth of the cornflour causes the dry ice to sublimate and the rising bubbles of carbon dioxide cause a frothing effect at the surface, reminiscent of a frothy strawberry milkshake.

Science Teacher Jacob Strickling creates a bubbling, frothing 'strawberry milkshake' using water, red food colouring, cornflour and dry ice.
Some red food colouring is added to a bowl of warm water.
Cornflour is then added and mixed. This produces a non-newtonian fluid which has some fascinating physical properties. The fluid is runny and liquid like when poured, but behaves as a solid when punched (as shown in the footage)
This mixture is then added to a glass containing some dry ice (-80 degrees celsius)
The warmth of the cornflour causes the dry ice to sublimate (turn from solid to gas) and the rising bubbles of carbon dioxide cause a bubbling / frothing effect at the surface, reminiscent of a frothy strawberry milkshake.

Some slow motion footage of the bubbles popping at the surface allowing the gas to escape is particularly fascinating.

Use this footage with some of editing / text and music to make an awesome Facebook post. People love recreations of food, particularly when the ingredients are totally different from the originals (milk, icecream, strawberries)
