We placed the oat flakes at the start of the maze and at the finish and set up a time lapse to see what happened. We took a picture every 8 minutes and checked after 5 days. As it has been quite hot after 3 days the plate dried out and Physarum as well. The salt speeded up the process. See the result in the video below. | ||

===Maze Experiment - second try=== | ===Maze Experiment - second try=== | ||
We want to improve the maze experiment so we started a second try. Normal agar plate was prepared again and also one full plate with the agar salt recipe. This time we printed a maze and cut out a stencil with coloured card board and put it in the liquid agar salt solution and let it sit till it cooled. We cut the maze out again and placed it in the petri dish with the 2 % water agar. We also painted a bit of the salty agar in areas we we don't want the organism to go. We placed oats at the end of the maze and the organism at the start. Time lapse is set. | We want to improve the maze experiment so we started a second try.
