Building a Human-Powered Boat with Recyclable Materials

AI Thread Summary
Recyclable materials suitable for building a human-powered boat should be strong and less dense than water to ensure buoyancy. Common suggestions include certain plastics and wood, which can provide the necessary strength-to-weight ratio. Glass Reinforced Plastic (GRP) is highlighted as an effective option for one-off designs and large mouldings, commonly used in canoes and kayaks. The discussion emphasizes the importance of material selection in achieving both performance and sustainability. Exploring innovative recyclable materials can lead to effective and eco-friendly boat designs.

why does it have to be less dense? certain plastics and wood come to mind.
 
GRP is frequently used for canoes and kayaks; it's ideal for one-off products and products requiring large mouldings.
 

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
