Or was it just from Liam’s mom walking?

I used gallium and aluminum soda can tabs to liberate hydrogen for a demonstration. After a lot of washing this chunky product is leftover. Does anyone have an idea of what it is and what I should do with it? A little more info I used tap water and ran a lot of water through it to wash away any of the aluminum, then poured out the clear water and more clean looking gallium onto wax paper, these dregs were the last out of the flask.
