In this video, 6th‑grade student Abhiraj presents his science fair project exploring how Beyblade design affects spin duration. Motivated by five years of personal experience with Beyblades, he devised an experiment using a digital tachometer to record the RPM of a single Beyblade as it accelerated, then timed how long it continued spinning after reaching set RPM thresholds (1,000 and 2,500 RPM). He systematically varied three components: the metal weight ring (light, medium, heavy), the tip shape (flat, round, pointy) and a custom 3D‑printed tip with three surface‑area modes (sharp, flat, round). His hypothesis was that reducing friction—by minimizing the contact surface area between the tip and the stadium—would increase spin time. Results showed the flat tip produced the shortest spin, while pointy and round tips performed better depending on metal weight; the 3D‑printed tip, despite being round, introduced wobble and reduced performance, disproving his hypothesis for that design. He acknowledges launch consistency as a limitation and suggests future work measuring Beyblade “power” (torque) and further tip optimization.

Hello, my name is Abhiraj. I'm in grade 6, and this is my science fair project. It's about Beyblades, and the title is Beyblades are more than just a toy. The reason I chose this project is I've been playing Beyblades for about 5 years, even though it's been a year, like, since I've last played it. My dad said, why not play— like, why not use this for your science fair project? I'm like, good idea. Um, at first I was gonna find, like, I was gonna test which Beyblade is like the most strong, but there's really no way to do that without some certain stuff I don't have. Then I thought I can do which Beyblade spins the longest, but how am I supposed to do that? As like, I can't just time myself because like sometimes Beyblades, like, you can launch harder or you launch softer. There's no way to always launch at the same speed. Until I thought, I can use a Tekometer, a digital Tekometer. And you may ask, how is that gonna help? So what a Tekometer does is it measures how many rotations per minute you can make, um, with this little white strip. So, uh, what I did is I, I ripped my Beyblade, I waited until the digital Tekometer— so I ripped my Beyblade, I put the digital Tekometer and use this, and I measured when— as soon as it reaches to 1,000 or 2,500 RPM, I'd use a timer and measure how long until it stops, and that would be my timing. So the certain parts of the Beyblade I used is I always use this one, this one Beyblade. So Beyblades are in 3 parts: the top, I just chose this random one, the metal Um, there's these 3. 1, 2, 3. This one being the lightest, middle, and heaviest. Um, after, like, so, and the tip, I chose this cool tip which actually has 3 modes: sharp, like pointy tip mode, flat, round tip mode, flat tip mode. So after testing a little bit Flat tip mode has like spins for the least amount of time, and pointy and round alternate depending on the weight of the metal. Um, then I thought, how can I maximize spin time? So my hypothesis was, um, the less friction, like the less surface area on the stadium The more spin time after stretching up. I was correct. Uh, so, um, I— so like something similar to this little cool tip. I, I have this tip. I 3D printed this, took this part off and put this in. Completely round, completely flat, and completely sharp. I thought Well, I— like, my hypothesis was this would spin for the longest. Turns out I was wrong, as this is a little wobbly. 3D printing is not always the best. And even though this is also wobbly, it's round, so it won't change as much. Being wobbly. Um. Um. So. Thank you very much for, um, watching. And later I am going to— like, in the future I might, um, find the power of the Beyblades, you know, the tops.
