有冇人試過用金屬樽做diy CO2?

只要是密封唔漏氣容器已經可以用黎做溶液儲存呀.

哇, 萬一唔記得咗擰埋樽蓋, 谷爆咗,
威力都幾係野吓喎!

安全起見都係唔好試

我想:用金屬樽做diy CO2可以成受更大的壓力,但其實膠樽已經可以受高壓(當然唔係好高啦~),只在乎你的密封技術做得好不好而已.

用金屬樽雖然係可以受大D壓力~
但有冇需要呀? 用得DIY 都唔會諗住儲幾十磅氣嫁啦~
而且, 用金屬樽冇用透明膠樽咁方便WO~

如果可以承受大壓力,加個開關掣,日間開,晩間關.點睇?

試搖一樽未開汽水，然後開蓋。
一樣道理。

係o羅...咁危險, 咪試呀.

你要知道，DIY CO2在容器內的CO2是不斷地產生，壓力是不斷地增加和鵬脹，有別於一般的CO2樽，樽內的CO2和壓力是漸漸地減低及釋放。兩者原理都背道而馳！
如果DIY CO2容器無適當的舒洩調節，與一個計時炸彈無異！

完全錯誤o既理論，DIY CO2 入面o既CO2係到達某一壓力時，有多就會溶入樽內o既溶液入面，即係到o左某壓力時，壓力就唔會增加，只會保持係某度數，同時係受壓下亦會抑制o左 YEAST o既活動能力，所以用膠樽亦無可能谷爆。

經過本人實驗，用氣壓錶測試過，點都谷唔到半個 BAR。

完全同意mftin說法,一定不會爆,我試過.因為依士粉在高壓下,不能生長,你可以試下關閉三五個鍾,然後開啟,你會發現的CO2沒有増多,反而弱了.
甚至出不到氣.

有無人試過加開關哩？

I guess no. Since liquid is incompressible, the yeast in the mixture is not suffering that high pressure as in the air part. Use metal container is phisically not any different with a plastic one but the question is how can you observe the reaction of the yeast? The next question is when you block the bottle in night time, the liquid will be suddenly purged out into your tank when you switch it open next day. Also, can you manage so well the same everyday for on and off time?

From the point of chemical view, the liquid in the metal container should be acidic, isn't it?
The metal will start a reaction with the solution ......and what is the output?
Unbelivable product......
