In the fire bucket “fire” is written in black or white color text, and the texts are in both local and English language. So even though the sand is meant to protect the bowl against the buildup of heat, it can actually make the bowl corrode a bit faster if it is exposed to moisture on a regular basis. This can be seen when you take an “empty” glass, turn it upside down, and try to push it down to the bottom of a sink full of water.

These buckets are sometimes used for the suppression of class D fires which are fires from burning metals such as magnesium, potassium, titanium, and zirconium. By experimenting and applying mathematics to physics, Stokes came up with a law that describes the movement of a solid through a liquid or a gas. The intensity of a fire varies because it is dependent on the oxygen, fuel, and heat available to it.

The tempura paint in this experiment represents the nutrients and dissolved particles found in the soil.

The idea that these four elements – earth, water, air, and fire – made up all matter was the cornerstone of philosophy, science, and medicine for two thousand years ( kids love to ask questions on the elements).

After another trip to the builders merchant you then discover the only builders sand they have is a red colour which results in your mortar being two different colours, leaving you in the quandary of whether to just use it as it is or try and colour match it using a mortar tone or other colouring method. Now that I'm all grown up with a wife and kids of my own, I hope to share all the knowledge I've gained over the years. The four elements were even used to described the four temperaments a person could have, and Hippocrates used the four elements to describe the four “humors” found in the body. The water flowing through the soil was able to pick up a large proportion of the “nutrients” and carry them with it through the funnel.
