Fun with vector math and physics! Learn the concepts of balance in a line or a plane. We call the plane, the X-Y plane. There is an X-axis and a Y-axis. So every marble has its X-Y coordinates.
– With Questions and Answers
– Easy to clean
– Exceed the strictest international toy safety standards

Game Goal:
To Keep the plate balanced by only using One marble.
● How to play with it:
1.First, use Your left hand to hold the plate in balanced.
2.For questions Q1 to Q24, place marbles on the plate as illustrated.
3.Then add One marble to balance the plate.
4.Release your left hand. Watch out! The marbles will fall down if you don’t get the right answer. Answers will be on the other side of the package.

You can also design your own question.
● Solution Steps:
Step1: The coordinate of the middle point is (0,0). And the coordinates of all the marbles are individual (X1,Y1),(X2,Y2),……(Xn,Yn)
Step2:X1+X2+……+Xn=X; Y1=Y2+……Yn=Y
Step3: The result of all the marbles is to put similar marble weight on the corrdinate (-X,-Y) point
