Discussion Overview
The discussion revolves around finding a food-safe method to create a stringy clear slime using polyvinyl alcohol (PVA) cross-linked with edible chemicals. Participants explore various alternatives and formulations that could achieve the desired properties for a movie project.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants suggest that edible alternatives to disodium tetraborate for cross-linking PVA may not exist or may not be effective.
- One participant proposes that the slime seen in "Charlie and the Chocolate Factory" could be made from various starches, gums, or soluble polymers rather than PVA.
- Another participant mentions that PVA with suitable macromers in water could potentially achieve the desired properties.
- One participant shares their experience with methylcellulose, noting it did not provide the right texture, being more yogurt-like than stringy.
- There is a suggestion to use carboxymethyl cellulose, with a note on its clarity and viscosity properties.
- Another participant recommends blending methocel with boiled okra extract to achieve the desired stringiness.
- A later reply mentions galactose dialdehyde as a potential cross-linking agent but expresses concern about finding a trustworthy food-grade option.
- Participants discuss the clarity of methylcellulose in water, with some noting it appears clear or translucent depending on concentration.
Areas of Agreement / Disagreement
Participants express differing opinions on the feasibility of using edible compounds for cross-linking PVA, with no consensus on a definitive solution. Multiple competing views on alternative materials and methods remain present throughout the discussion.
Contextual Notes
Limitations include uncertainty about the effectiveness of various proposed materials and methods, as well as the dependence on specific formulations and concentrations to achieve desired properties.
Who May Find This Useful
This discussion may be useful for individuals interested in food-safe slime formulations, special effects in film, or those exploring edible polymers and their applications.
