I have found the perfect bowl for incoming vomit!
Plastic - check
Deep/large enough to contain splash back but not so deep as to be unwieldy - check
Spout to easily empty - check
Dishwasher safe - check
Plus the handle on one side and the spout make it easy to hold support on a lap.
It's showing out of stock online but I got it in a store today.
I'm sure it's great for mixing too.
