Thank you for sharing this! It’ll definitely help me when I try this experiment at home. EDIT: just watched both videos and not sure how the second one could be used outside of the water? The first video with the potato seems great however you’ll have to change bottles every 4 hours, and I’m not sure if this flow rate he’s to 500 ml/h like used in the actual experiment? Would love to chat with you about this though so I’ll be shooting you a message!
