Purple!

@Barney Not really harmful, unless you were insisting on putting your face right there, and taking deep breaths. Here’s a fun youtube entry on how to create your own purple smoke (kids, don’t try this it home unless you are very, very careful).

@Barney Heck, here’s an even better link (because it has words, and a decent explanation).

@Shrdlu No deep purple breaths, huh? (Thanks for the info.)

@Barney @Shrdlu What could go wrong, kids are always very, very careful.

@Barney @llangley @Shrdlu My first concert at The Palace. They were the first band of a triple header.

@Barney Does anyone else see the smirk-level humor/irony in “Barney” asking if something purple is harmful???

@zinimusprime Hey now, be nice.

you’re an all-star

@Barney @Mothersnakes @Shrdlu What’s the worst thing that could happen?

@blaineg We do not want to lose the purple.

That’s what Dad told Mom when he gave me the chemistry set.

@lseeber Oops.
