Expanding Foam!

I was finding it hard to create a sponge like texture and the colour was really hard to make. Ive never used expanding foam before and didn't know if it would work so thought id try it. I used a 2 part foam which i mixed together and poured straight into cupcake cases and tart tins. As this was the my first time using it i didnt know how much i had to pour in and how much it would expand so it was an experiment. Here are some images of the stages i went through. I was overly pleased with how they turnt out the sponge looks really realistic and once decorated they will look great!!
