Most newtons cradle made with small diameter stand and fishing line, make it cheap and the string easy broken. this made with largest diameter(8MM) of stainless steel, and strings made with SUS 304 stainless steel instead of fishing line, as fishing line easy tangling and broken. Strings in the hole fixing to the top bar which making hand comfortable when grabbing it and also good looking. As metal string are harder than fishing line, so it much more stable than fishing line when it's working.7 pieces of 20MM diameter metal balls.
