Future Clothes Could Use Engineered Scents to Change Mood and Enhance Memory

These futuristic clothes will be able to put you into any mood you desire. What they do is they give off special aromatherapy fragrances that are each designed to put you into a specific mood, whether it be calm, focused, happy, etc. Also, biometric sensors can be attached to the clothing so that the wearer's heart rate and stress levels can be detected. According to the stress level, the appropriate aroma will be emitted to keep the wearer at a happy medium. Also, as the sense of smell provokes the memory more directly than any other sense, the concept clothing can also help keep elder people's minds stay sharp. The person behind this idea is Jenny Tillotson, who wanted a scent bubble to follow behind the patients in the hospital to get their minds off the "smell of death", leading to a speedy recovery. As of now, the idea of scented clothing is purely conceptual, but Tillotson is working hard to make it a reality.

Gravity Powered Car

First, I Got four empty XS energy drink cans, two large, and two normal size. Then, I glued them together to form the base of the car. After that was done, I drilled holes into them for the axels. For the axels, I used two pencils. For the wheels, I used the tops of yogurt containers, two large, and two normal size. I inserted the axels into the body, then glued the wheels firmly to the axels. After that, I glued nine AA batteries to the bottom of the car for extra weight. When this was done, I covered the two front cans with plastic wrap. On top of the plastic wrap, I glued a bent piece of cardboard to make it more aerodynamic. Then I covered the open sides of the tip of the car with tin foil. After ths was done, I gave the wheels more friction with rubber bands. When all this was done, I decorated the car with fire and spray paint.
