# Key Points from IRC Log

• Microfluidic device development was discussed, with kanzure seeking advice on actuation methods for "sharpie microfluidics" devices, considering options like thermal gradients, pneumatics, and electricity-based approaches.

• Gene shared information about droplet microfluidics and a technique for moving fluids uphill using electrodes, with links to research papers on electrohydrodynamic flow in suspended liquid films.

• A discussion about error propagation in physics measurements took place, covering how to properly calculate and represent uncertainty in velocity calculations from time and distance measurements.

• The concept of growing algae in bubbles as a potential solution to filtering problems was briefly explored, with considerations about light penetration, waste removal, and spatial confinement.

• Kanzure expressed disappointment about the DIYbio community's focus on GM food debates rather than engaging with his microfluidics post, indicating tensions between different interests in the biohacking community.

• Materials for microfluidic device construction were discussed, including UV-curable glass adhesives and hydrophobic surfaces like Rain-X for potential use in these devices.
