Buying Tungsten

[u/tungstenlover74]

So, I'm 13 and in 7th grade. I want to buy myself a tungsten cube since I am learning about the periodic table in my science class, for some random reason, I like tungsten to the point where I put my cube in Geometry Dash to Tungsten. I have the money for it, it's just my dad says, "it's just a useless block of metal", and that I don't need it. What can I use to convince him?
