Very easy to do.
I did have a couple of incidents though, probably lucky I didn't injure myself.
One in particular scared the

I remember making hydrogen in high school chemistry class. We filled small bags with it and then ignited them. The bag with 100% hydrogen didn't burn very violently. The bag with 50% hydrogen, 50% air made a nice bang.
