Project 213 (P213 for short) is an innovative yo-yo design by Doctor Popular. The idea is just to create a hybrid of yo-yo and top.
- The initial Project 213 used ProYo parts to make the yo-yo and a Spintastics spin top for the tip.
- The Renegade was often modded to have spikes come off the sides (known as the Terror Yo).
- YoYoJam marketed Doc's P213 using their yo-yo and spin top parts.
- Freehand 2's were successfully modded with Bearing King tips on the sides.
- In some cases, yo-yos like the Duncan Trans-Axtion and the Henrys Viper were used for constructing P213 yo-yo/top hybrids.
- Dif-e-Yo produced the Spike-Fly and Gladiator yo-yos, which come with spikes on the sides.
Check out Sector Y for some videos with the P213. The website for the College for the Easily Amused hosted their first video, which featured the P213. Some of the old Spindox videos featured the Terror Yo. Chris Neff had also experimented with P213.
Overall, P213 is considered a novelty concept and very few have ever pursued it seriously in modern yo-yoing. However, in comparison to conventional spin top play, P213 actually offers several advantages, because the yo-yo component will allow the top to rewind the string after each trick. Whereas traditional spin tops require the user to wind up the string after every single throw, P213 can execute spin top tricks with the added bonus of being able to return to the hand like a yo-yo. P213's presentation was oriented towards the yo-yo community rather unsuccessfully, because no one wanted to have to spend time and energy putting one together. However, it would likely have a huge impact if it were introduced into the spin top community.
