This work-in-progress paper submitted for the poster session of the K-12/Pre-college Division describes a new and unique set of hands-on activities called "brainstorming with yo-yos" that was designed as a recruiting tool in a high school outreach event to inspire high school students' interest in learning physics and pursuing post-secondary education in science, technology, engineering, and mathematics (STEM). A total of 122 high school students, including 91 males and 31 females, from different school districts across the author's state participated in the present study. During an one-and-a-half-hour "Phun" with Physics session period, student teams identified, via brainstorming, more than 50 physics concepts that are related to yo-yos. All participating students enjoyed "brainstorming with yo-yos" activities. In their written comments, many students used the words and phrases such as "fun," "play," "hands on," and "real life" to describe their experiences with these activities. The future work will focus on collaborating with K-12 physics teachers to incorporate these activities in the formal K-12 course curriculum.
