This morning, before walking to work, I went into the bathroom to put a little sunscreen on my face.
Squeezed the tube and nothing came out. Put the cap back on, squeezed from the sealed end towards the cap, then tried to get some out again.
So I got out the big scissors and a flat blade knife. I wanted sunscreen and I wasn't going to be denied!
Cut the tube twice through it's middle and used the flat blade knife to scrape out the sunscreen left inside. (I do the same thing with handcreams and hair conditioners.)
