do these beautiful throws tilt while spinning? because they look really plush, but look prone to tilt because of distribution of sand during spinning.
I’ve always wondered
I think it would be fine as long as the amount of sand in each half is approximately the same. I don’t think it can move from one half to the other while the yoyo is spinning.
Wow, just discovered this. So cool – the middle and sides combined make a functional hourglass! You can fill or remove the sand by taking the halves apart 
But 77g?
What has @3yo3 been up to lately?
