First experiment:Spring onion root
At the very beginning of the course I was not sure what to start with but the topic of rot and decay has always been fruitful. The start of this small experiment was done at home and was simply cutting off the root of a store bought spring onion and placing it in a petri-dish wish a mixture of table salt and tap water in hopes of speeding up any chemical changes.

After a substantial amount of time in my room by the window the changes were not very noteworthy. Yellowing/browning and deflation, the root seemed to be losing moisture to the overly salted water.

On 27.11.2018 the root was put into an incubator at 20 degrees Celsius however this was for some reason increased to 30 at some point in 5 days so it dried out more than expected. Least blurry photo available was black and white...

The root interestingly seems to have been pulling water into it even after over a month of being cut off of the rest of the plant. Shown by salt crystals that formed on the upper surface of the plant and patterns of salt that crystalised towards the root as the water dried. Could be an interesting way of portraying how the roots are structured/evolved to passively absorb.
