Instead of the sides being triangles, I decided to change them into smaller rectangles and tried to see how that would impact the movement. Because the rectangles are smaller than the body, they move upwards when inflated. However, because I did not close any space between the triangle body and the rectangles, the rectangles failed to completely fold inwards.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/adjusted-example.mp4\"><\/video><\/figure>\n\n\n\n<p>My own samples:<\/p>\n\n\n\n<p>I originally thought we needed to make 3 of our own samples. While making them, I had more ideas and I ended up making a bunch of random but similar samples. My favorite one is the bracelet-like form that could also be flipped inside out. <\/p>\n\n\n\n<p>Bracelet Example:<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-video-1.mp4\"><\/video><\/figure>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-video-2.mp4\"><\/video><\/figure>\n\n\n\n<p>For this sample, I first cut out a long piece of plastic material (around 14 inches). I then drew a rectangle leaving only 1 cm from the outer edge of the cut plastic piece. Next, I made two folds. First down the center and another 1.5 cm away from the first fold (in another direction). See the below image:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"506\" src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-1024x506.jpg\" alt=\"\" class=\"wp-image-6322\" srcset=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-1024x506.jpg 1024w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-300x148.jpg 300w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-768x379.jpg 768w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-1536x759.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-2048x1012.jpg 2048w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-973x481.jpg 973w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/My-example-pic-1-508x251.jpg 508w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Now that I have the folds, I drew a straight line on the fold (leaving around 4 cm between the line on one side of the rectangle and 2 cm between the other end of the line and the other side of the rectangle). I then cut a small hole in the top of the sample (the side with the marked lines) and inserted the plastic pieces that allowed air to go into the sample. After that, I used the large impulse sealer to seal the marked line at the center of the sample. Because I did not want to seal the entire center, I taped a piece of cardboard paper to the bottom of the plastic between the center line and the edges of the rectangle. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"445\" src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-1024x445.jpg\" alt=\"\" class=\"wp-image-6323\" srcset=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-1024x445.jpg 1024w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-300x130.jpg 300w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-768x334.jpg 768w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-1536x667.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-2048x890.jpg 2048w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-973x423.jpg 973w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2022\/wp-content\/uploads\/2022\/02\/my-example-pic-2-508x221.jpg 508w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>I then folded the sample in half and sealed the two long ends of the sample together with the impulse sealer.
