Dimensions for the prototype dumpling:
- 1 layer of skin (~7g)
- Playdough filling (~20g)
Forces and their impacts on the dumpling skin we bought:
| No. Of skin | Force (kg) | Time (s) | Remarks |
| 1 | 1 | 3 | Cannot. |
| 2 | 3 | Dumpling can close well (a bit ugly but no choice), limited by the “sharpness” of the grooves of the mould | |
| > 3 | 3 | Still about the same “closeness” as 2 kg. Might need > 5 kg force or change skin. | |
| 5 | 3 | Slightly better. | |
| 2 | 4 | 3 | Cannot close. |
