It is the effect that when grains of different sizes are mixed together and the mix is shaken the bigger particles will move to the top You can also do this experiments by making some mix yourself like mixing rice and beans Build a well with gravel and sand and learn where the water we use every day come from

Cover the glass bowl with the plastic wrap You want to make sure to stretch the plastic wrap very tight across the top of the bowl Wrap the rubber band around the bowl to hold the plastic wrap in place Place the bowl very close to a speaker or CD player Sprinkle some salt on the plastic wrap Play your favorite music through the speaker
Vibration sorting machine for aggregate crushed sand gravel published date 08 28 2022 Aggregate is a granular material that acts as a skeleton and fills in concrete and mortar The fine aggregate particles are between and 5 mm in diameter Natural sand such as river sand sea sand and valley sand is generally used
The frequency of vibration increases with stiffness and decreases with mass So when you add mass by filling with sand you decrease the natural frequency of vibration or the tripod/pier This means that any given size exciting force a bump etc will result in greater amplitude of vibration Get rid of the sand Al jeff65
