How do you build a Volcano? - Comments

i've never actually built one but i think clay would work and then add play-doh for color or just for fun =)

I had to do that for a school project I just used play dough I wouldnt suggest it unless you can harden after you build it not before other wise what was the use of buying the play dough if you cant mold it but you could probably use floam to i should have tried that but either use floam or play dough or paper and glue on to a plastic cup and attach it to card board. Sorry if this comment is way long.

i dont know

we dont do anything that practical
