For more detailed step by step instructions have a look at my second go at this activity Mister Maker splat bugs take 2.
I like Mister Maker and we do use it as inspiration sometimes. I generally have to simplify the projects down and I rarely have all the materials which can be a bit annoying. I do like the segment 'make it in a minute' – if Mister Maker can make it in a minute then presumably we can make it in half an hour. How do you feel about Mister Maker?
On a side note you may want to check out the Mister Maker website. It has a cute gallery of projects that kids have made with links to the relevant segment of the show.
