I recently acquired an unlikely but exceptionally effective Aeropress espresso coffee maker that consists of 3 simple plastic parts. I do still miss the hum of our old Expobar espresso machine that died, but this new set up makes an awesome Americano and has the added advantage of being portable for camping or travel.
The only problem, albeit a small one, was that I needed an efficient way to transfer the coffee grounds from our grinder to the Aeropress. I wanted something reusable, easy to wash and simple to store. The idea for a fused-plastic, folded scoop was born.
I have made things using fused plastic in the past. The process for fusing plastic is very simple, although it can be a challenge these days to find plastic shopping bags. As you can see from the photos, there is only one store I frequent here in my town that still uses plastic bags. I cut off the seams and the handles of 4-5 bags and stack the flattened layers of plastic between two sheets of parchment paper. Using an iron on medium heat setting, press firmly and evenly across the pile of plastic. The plastic will quickly melt and shrink into a solid sheet of plastic. Keep ironing, turning and flipping it occasionally, until the sheet of fused plastic is no longer visibly shrinking. Once the plastic cools, you can trim off any irregular edges.
To make my scoop, I trimmed the plastic sheet into a long rectangle. Then I folded it in half in both directions as well across both diagonals. The open, creased rectangle is laid under the spout of the grinder to catch the grinds. By pinching half of the long rectangle together, a scoop is formed on the other half, making it easy to pour the grinds into the coffee press. The fused plastic is durable, easy to wash, and dry, and fold to store away.
What have you created out of necessity – the mother of invention?
