The hail-pad I designed has the ability to show size, number and direction of these hail-stones. Additionally, with the two-layer modelling clay system, it can be derived from the hail pad whether these stones were travelling at high speeds on their descent to earth, as they would expose the under-layer of clay in their imprints. This hail-pad is relatively water-proof and will not dry out due to reasons explained further in this instructable :)
In the end, creating one of these hail-pads costs roughly $2.09 AU ( NOTE: you can reduce the price significantly by $1.00 (therefore making it $1.09 AU) if you wish to not use the "two-layer clay" system but rather just one layer of clay, I believe it still provides accurate results). So without further to do, lets begin making one!
Step 1: Materials Required
- Two different coloured, medium-sized balls of soft modelling clay (approximately equals $1 each)
- One plastic plate (approximately $0.083)
- 20 cm of plastic wrap (approximately $0.01)
The reason I chose modelling clay is because it is designed for handling and playing with, therefore it is not meant to harden or dry out under many conditions. Thus modelling clay appeared to be the best choice for imprinting impacts of hailstones regardless of weather and temperature.
Step 2: Creating the Layers of the Pad
By smoothing out the clay, you are increasing your chances of getting more accurate readings and thus, better results.
Step 3: Applying Plastic to the Hail-Pad
This can be an optional step if you please, as I tested varieties of these plates and the clay appeared to be water-proof and out of personal preference, I would not have the plastic sheet, as it provides more accurate results.
Step 4: Taking It Out Into the Real World!
Note: Due to the pad being made of clay, you can possibly reuse the pads by simply re-flattening the surface of the exposed clay for later usage. Also, if you want to keep records of various readings, you can create molds from the clay and then create rubber or silicon molds of your readings!
Step 5: Final Thoughts
Thanks for reading this instructable, I hope you have enjoyed it as much as I have had making it :)
