To put chemicals in a party bag?

[BirthdayPlans]

I'm thinking of doing a science party for DS. Children aged 7-9. Debating the idea of doing a couple of experiments with them. DS wants to grow crystals but that takes too long. But I did wonder about us growing some seed crystals and then giving them out with a small sachet (plus instructions plus warnings) to grow them larger at home.

The shop packaged sets are a bit expensive to buy one each, so it would be cheaper to buy a larger amount and package it myself.

Yay or nay?

I think it’s fine. I put water beads (www.amazon.com/Clear-Rainbow-Growing-Polymer-Balls-12/dp/B007N5VCCK) in DD’s science party bag when she turned 6 (I think). I just stuck a big ‘do not eat’ warning to the bead sachets and didn’t get any complaints. AFAIK all the kids survived.

@Comeymemo AFAIK

I love your idea, but I agree with p.p’s, there’s too much potential for something to go horribly wrong - unless as others say, the chemicals are absolutely not harmful if ingested.

And “would it be cheaper to buy a larger amount..” Be careful, you could end up on some terrorist watch list (only joking).

You made me laugh so much, “chemicals in a party bag”. Thanks!
