Tinker Nest

I was looking for some design ideas for my half-yearly designing project when I came across this puzzle made on Pinterest. I loved it and decided to make it for my submission. This puzzle is not only fun to solve and beautiful to see but also apt for beginners like me. Things We Need Tinkercad account(It's free) Slicing Software 3D printer Filament of choice (I used Blue and Black) Digits 8 I started by designing digit 8 first simply because it is easy to make among other digits and it may be used as a base to make other digits, as you will notice later. To make digit 8 : Drag a sold Box to the workplane and adjust its measurements so that its Length to 40 mm, Width to 24 mm, and Height to 8mm. For the inner holes of the 8, use two hole cube with Length and Width = 8m and Height = 10mm. Now, drag 2 hole Roof and rotate them so that they are pointing toward the main body of digit 8. To cut off the corner, use 4 hole Box and rotate it at a 45 degree Finally, select all the shapes and...

6H2O + 6CO2 + Light Energy ----------> C6H12O6 + 6O2 This is one of the equations that are most important for our existence on earth. This equation is the representation of the chemical reaction that takes place during photosynthesis in plants. Basically, photosynthesis is the process by which plants convert the sun's light into energy. Photosynthesis is one of the most important processes on this planet; it is the foundation for the entire food chain and provides humans with breathable air. In this project, we will conduct a simple experiment using spinach leaves to demonstrate that, in the presence of light and carbon dioxide, leaves produce gas bubbles. While we cannot prove in this experiment that these bubbles are oxygen without a gas probe, but when we investigate further and perform this experiment in the absence of baking soda(sodium bicarbonate), which provides carbon dioxide, no bubbles are released.
