Menu and Popcorn Buttons

This is how far I have got on the popcorn project. I have nearly finished my menu, however I still need to add two working buttons to the last two options.

I have also completed my first sequence on how popcorn pops. I just need to add text on the stage to help demonstrate the question.

Here is a screenshot of my second sequence on how popcorn is made, again I still need to add the text.

I have started my third sequence on how a steam engine works, however this is taking a bit longer as I am attempting to make the steam train run across the page. Here is what it looks like so far:

Overall I have made a lot of progress, there is only a few more things I need to add to make this project complete.
