TWO WAYS TO REDUCE PLASTIC

However, there are two ways to reduce the amount of plastic used. 

One is to reduce the number of plastic cups used, and the other is to make plastic cups of the same volume less plastic.

PLASTIC CUP​​​​​​​

In other words, using plastic cups that use less plastic can reduce plastic 

even with less effort. New plastic cups should not compromise the ease of existing plastic cups either. To do so, these conditions must be met.

SURFACE VOLUME RATIO

Because the volume of the cup was fixed, only the surface area was calculated and the reciprocal of the surface area was graphically represented. Calculated with a graph calculator, we predict that there will be non-extreme cup forms between 3.0 and 3.5 where sharp gradients are formed, and calculate them back and forth.

GRIP EXPERIMENT​​​​​​​

Evaluating grip experience by huristic device.  If you scientifically solve the grip, there will be various methods such as friction coefficients and vectors. However, the assessment of the grip experience relied on heuristic devices, judging that, at least in experience, practical testing should be a priority over all of them.
