I wasn’t given a lot to go on for this one, just asked to make something science, chemistry or geology. At first I struggled with what to as it’s a small cake, only 6" & I always seem to end up making details life size….lol. I went with making the cake to look like the lab benches in our chemistry department. I topped it with a bunsen burner that has a candle in it to look as though it’s lit & alongside that is a weigh boat with colored sugar. Happy birthday is spelled out using elements from the periodic table. All the details are made from fondant & gumpaste.
