Ferdous commented on Collapsible Keychain Cup

I really like this accessible cup idea with the inclusion of keychains! Though I do have a inquiry: Even though it is reusable by major companies, would it be reusable regardless of weather? It may be beneficial to the public overall, though I think that weather variables should take into account of the fluids of the cup if it would be truly accessible, one notable example being temperature as it can alter the preservation of heat or cold (like a thermos).


Ferdous commented on Cuffea

I really like this idea of using old coffee materials to make biodegradable cups, though for this Cuffea cup my question would be how would this cup make sure that its materials don't impact the taste and feel of the drink when in use? I get that the texture and smell would be similar to coffee but I'm curious as to how the taste and eventually contamination of the fluids of the cup would be impacted. Are the materials from the membrane certain to not leave towards the fluids?
