- **Ultra-cheap pressure vessel experiments**: Participants compared PET soda bottles (2 L, 30–40 g) to latex balloons and steel propane tanks, noting that PET survives ~800 kPa at room temperature and can hold butane for months without measurable leakage, while balloons can be over-pressurized from 2.5 kPa to 25 kPa with reinforcement.  
- **Safety debate on hydrocarbon storage**: Concerns were raised that PET may soften above ~50 °C (butane vapor pressure ≈ 5 bar) and that some polymers could be chemically attacked by butane; steel remains the norm for larger quantities due to static dissipation and flame resistance.  
- **Chemical availability puzzle**: n-Hexane and butane are sold in PET containers in some regions, yet n-pentane is reportedly hard to source, prompting tongue-in-cheek speculation about clandestine drug-lab demand.  
- **Hemp-seed oxidation discussion**: Advice given that shelled “hemp hearts” oxidize at roughly the same rate as whole seeds; opaque, foil-lined or metal/glass packaging is recommended over clear plastic bulk bins to extend shelf life from 3–4 months (pantry) to ~1 year (refrigerated).  
- **Reference data shared**: Vapor-pressure charts and NIST Antoine-equation plots for butane were linked to quantify pressure–temperature relationships for DIY storage calculations.
