Fainting

So me and my sister were playing with this stuff called Oobleck, which is corn starch mixed with water to create something that seems hard, but turns into liquid as you pick it up. But then I started to feel dizzy, and I almost fainted. I remember my hands were covered in dry corn starch, but then I felt dizzy, and I opened my eyes I was leaning over the toilet breathing deeply with water and my hands were clean.
