Invention Design Reflection

I believe my most successful part of my invention was making the bumps on the underside of the needless injection tool. They look realistic and seem to be all in proportion. I believe that this part of my invention shows how needless injection can be done and go through your skin, rather than puncturing your skin. The part that I found least successful was the cartridges at the top of the tool. They were hard to smooth out and didn't shape in the way I wanted them to look. I think that needless injections would be a great invention for the future because, not many people like getting needles and many people have a fear of needles. Using this tool would eliminate their fear and allow people to get injections without the tool being invasive or going into your skin. This would make it easier for children and even pets as well in the future. Children and pets also seem to have a fear of needles and needles may cause pain to people, thus their fear of needles has occurred.
