Part 1 of 3: 2.2mm vs 2.0mm TT sponge thickness - Physical properties and quality control issues?

This is the first in a three part series looking at the difference in performance between 2.2 and 2mm table tennis sponge thickness on the same make/model of table tennis topsheet - using Giant Dragon Maxspin. In this video we concentrate on the physical differences between two sheets of the same table tennis rubber but in 2 and 2.2mm sponge thickness and discover some unexpected variaions in what should be the same top sheet. In particular we look at dome / curl, top sheet, sponge elasticity, grip, tacky test, weight and cut open some bubbles which formed on the top sheet of one of these rubbers to find out why the bubble had formed. We also ask ITTF Chairman of the Euipment Committee Mr Odd Gustavsen some questions about the variations we found and the authorised rubber list. Other Videos in this series of three are: Pt 2 of 3: Robot testing, comparing throw height, trajectory and speed as well as spin reaction and reasons why you can't consider sponge thickness in isolation ie why you will also need to consider things like elasti city, pip structure, top sheet hardness, tackiness thickness, role of blade etc 3. Human testing - demonstrates how different people can rate the same rubbers performance.differently for serving, return of serve, pushing, top spin drive, block, power loop, brush loop, smash and chopping and questions the relevance of generic speed, spin control ratings. These videos will be released staggered. Part 2 to be released some time next week.
