The porcupine needle can be used to help create a less painful hypodermic needle. The prototypes can be used to determine which quill goes into the skin. The amount of force will be measured as well as what happens when the quills are put into the skin. In the first prototype the original porcupine quill is being compared to the hypodermic needle. In the second prototype a porcupine quill that is larger than the original is tested against the hypodermic needle. In the third prototype a porcupine quill that is sharper than the original is being tested against the hypodermic needle.

Porcupine Quills To Less Painful Hypodermic Needles

# data[].attributes.body
The adaptation that will be featured in my design is the type of quill that is being compared to the needle. I will compare a hypodermic needle to the original porcupine quill to see the effects that take place when when injecting it into the skin. I will then test the effects of a larger quill to the hypodermic needle. The third prototype tested will be a sharper quill to the hypodermic needle. This adaptation will show which quill produces the best results when being compared to a hypodermic needle. This research will help to provide a less painful hypodermic needle.

My design is going to be a less painful hypodermic needle from porcupine quills.  I will make these needles to help people that have hardships using needles to inject or extract substances from their body. These needles will be created after studying the effects of porcupine needles being in human skin. I will have to monitor what happens when porcupine quills are put into skin. I will need to measure how much force it takes to pierce flesh and how much force was required to remove the quill from flesh. I will need to test the quills against an 18-inch hypodermic needle. Once these tests have been conducted this information can be used to construct a less painful hypodermic needle.
