Weather balloon

Hey everyone, i’m planning on launching a weather balloon in 2 weeks, i’ve ordered everything and will assemble it soon. I was wondering, has anyone who is currently doing aerospace done one? And like do you guys think it’s a good extracurricular or like activity that a university will see as nice? I want to study aerospace engineering and I wanna stand out, other than the weather balloon I plan on modeling a wind tunnel for experimental uses. Let me know what you guys think of a weather balloon and if you could suggest other activities. I went into the basics if CFD, well kind of jumped in into angle of attack of airfoils which is very basic. I plan to learn more.

Thanks in advance for any suggestions and recommendations!
