For Elon University senior, Maddie Tamblyn, coffee is something that she would like to enjoy at a warm temperature, even if three hours have passed by.

Hypothesis 

Summer internships are rough on its own, arriving at your desk for work with a cold coffee is another story. This is when Tamblyn came up with her  new invention, MadDogg Heat Sleeve.

"I would grab coffee on the way to work and by the time you got to work, badge in, got up to your desk and actually started working, my coffee would be cold. I found I was waisting a lot of money because I'd end up throwing it away," said Tamblyn.

After a summer filled with making prototypes, Tamblyn came back to school in August ready to make a name for her new invention.

Thesis Statement 

Winning a pitch competition on Elon's campus with three other students eventually sent Tamblyn to the place a young entrepreneur dreams about visiting; Silicon Valley for another pitch competition. Tamblyn made sure that she was going to be one of the people to pitch their idea, and best believe she was picked.

Tamblyn received the highest scores at the competition and won.

The Product

The MadDogg Heat Sleeve is not your ordinary cardboard sleeve. Most people use a coffee sleeve to keep their hands from getting burned by the temperature of the coffee, so the outside of MadDogg is made of cardboard for that reason.

The inside of the sleeve is what is most unique. The inside is not much thicker than a typical sleeve, but it sustains the heat and maintains the temperature. A normal coffee is poured at about 140 degrees and most drink it at 120 degrees. Tamblyn feels that coffee just doesn't taste the same once the temperature drops under 100 degrees.

Testing temperatures

When using the MadDogg, three hours can go by and the coffee temperature would still be around 117 degrees. "The only use of the current sleeve is to protect your hand. It doesn't heat or keep your coffee hot. Mine is doing what theirs is doing and keeping your coffee hot," said Tamblyn.

"The first time I used the MadDogg, I was surprised in how well it actually worked. Not only did my hand never get burnt, but as time went by the coffee continued to stay warm after a couple of hours went by," said Elon Student, Molly Smith.

Conclusion

Tamblyn continues to keep her creative juices flowing as she embarks on new projects. With trying to keep most of her focus on the MadDogg and developing it, she still has a little something in the back of her mind. "I haven't told anybody. But in the next few years, I want to make it happen. It has to do with rain, I can tell you that."
