From June 19th, Phase 2 of Post Circuit Breaker was implemented which meant that a group of maximum 5 people could go out. Eateries and a lot more shops were open. This meant that our group could finally meet outside of Zoom, in person to discuss our project. More importantly, we needed to get several […]
In this project, we will research the way to automate the process of clear ice making, and design a machine that can make clear ice from scratch. We also aim to allow the freezing of clear ice into different shapes through different molds beyond the typical cube shape in standard ice maker
Directional Freezing is a simple method to make crystal clear ice by controlling the direction that water freezes. It mainly consists of allowing water to freeze into ice from only one direction (one side of a container) and the ice will be clear until the very last part to freeze, where impurities and air bubbles […]
To remove impurities from water, water purification is required. Through our research we found out that there are 2 ways of doing so: Distillation and Reverse Osmosis. Both ways produce pure water – however, through further research it was proven that freezing technique is more important than using pure/distilled water. Preliminary experiments by Alcademics that […]
Ice is usually not clear because light rays that pass through ice are scattered by mineral impurities and air bubbles that are trapped within. Light can also be scattered by small ice crystals that results in higher surface area for light scattering. Impurities and air bubbles get trapped because water normally freezes from all directions […]
We were finally granted permission to go to lab, though only maximum 2 per group, to start working on our projects. Though we did not have all the materials that we ordered yet, we decided to still make a trip down to the M&T Lab to look at the materials and resources available in the […]
After meeting with Dr Ho, we realised that we were unsure of many things. We also had worked out our own water system model, and wanted to ask Tony for a second opinion. As a result we wrote out a bunch of questions to use as a guide during our discussion with Tony. Here are […]
After many group meetings and discussions on Zoom, as well as some consultation with Tony, we managed to narrow down our project idea to making a crystal clear ice maker. We tried our best to do as much research as possible to understand the mechanics behind making an ice maker and why clear ice. It […]
