I accidentally made methane but realize that I should’ve made propyl ethanoate. Unfortunately I don’t have all the supplies for this as I live in a boarding school on a mountain in Switzerland and it is hard to get materials. I have attached a photo of my methane and a photo that is not mine of a propyl ethanoate 3D model. Thank you

I originaly used blueberries as C atoms, but they weren't strong enough, so I instead used Baby sweetcorn as C. Putting a cocktail stick through one caused it to randomly burst into 2. The Pea H atoms kept falling out, and eventually one of the cocktail sticks split, but I didn't notice until I was taking pictures, so now there is a C C bond that is single on one end and double on the other. As I had just finished, a piece of sweetcorn exploded (but it still kept everything together), making for a worrysome time taking pictures.

Anyway,
Carbon - Sweetcorn
Hydrogen - Pea
Oxygen - Radish

I wanted to show the lone pairs on the O, so I used cocktail sticks I broke in half (you can only see one on the C-O-C bond, but it is there

First model:
I've used salt dough colored in bulk with black ink (actually it is a very dark mauve even though it is supposed to be black) for the carbons and red lipstick for the oxygens and kept raw for the hydrogens. The bonds were made with teeth sticks. The dough balls were too heavy and some bonds have collapsed. I took the photo while the model was still wet it may be more stable after drying in oven.

Second model:
I have dried the spheres of salt dough in the oven for almost an hour at 75°C before assembling them with the teeth sticks. We can notice few minor cracks but the overall model is more robust and can stand by itself.

Future enhancements:
Use glue to stick the balls and the sticks. Make the holes in the dough when half-cooked. Use a protractor to mesure the angles. Use less water to get a less ductile dough. Add a tiny amount of oil to avoid cracks. Use acrylic painting to get a more bright colors.
