I needed a rubber spatula in uses for mixing in a small narrow-necked bottle. Therefore, the head of the spatula needed to be flexible, and if it were to get lost inside, cheap and easy to reproduce. I thought making the product would be easy, but then I realized that I didn't have any Sugru on hand. I also tried making mikey77's "Oogoo", but the only silicone caulking I had was GE II, which cannot be used to make Oogoo. Without any way to make my own rubber, I had to turn to a common substance: hot glue!! Today I will be showing you how to make your own useful mini and disposable rubber spatula using hot glue and some other common household materials! It's great for use in labs, for artists, and many other ways!
