Hi Katie. Regarding the Kinder egg for that penguin project, I'm not sure where you are located, but if you're in the USA they are illegal to sell. It's a chocolate egg with a toy inside, a total choking hazard. Sort of sucks, I'm in the US too...but I think you'd be able to find something else to use if you really wanted to.
I saw your comment on my shaving cream paper, first I just swirled it around and made a circle of color and then put my skewer in the middle and pulled outward.
