In accordance to one of the Citizen Science challenges from SciStarter.com
, it describes to create an inexpensive and efficient type of hail-pad for organizations such as the CoCoRaHS
, that can accurately display the size, orientation and number of hailstones throughout a hailstorm. This challenge caught my eye and prompted me to try and develop my own alternative design of a hail pad without any Styrofoam and foil, as apparently they have tripled in cost throughout the recent years (I've seen places that sell Styrofoam squares for as much as $5).
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!
