mentos volcano without mentos

[woodencoffeetable]

(or diet cola)
what else can we use?
we have a limited amount of baking powder, no soda of any type.

and no vinegar

Do you have diet coke?

nope, no fizzy drinks at all. and no mentos either.
we have yeast. sugar. flour

(might take too long)

The yeast reaction will take too long for what you're after.

Possibly another acid? Lemon juice? with your bicarb I mean.

Baking powder with ketchup and some washing up liquid?

You could even add in some salt

lighter fluid?

I know, I ask dc do build one again with enough space for the mini blender...

If you have lighter fluid, bicarb and icing sugar you can do a pretty good experiment with that!

Mix sugar, bicarb together, pout onto sand or dirt, cover in lighter fluid and set it alight. A reaction occurs and makes the sugar mix look like a creeping black monster. Smells like marshmallows too.

no bicarb, just baking powder.

ohhhh I have an idea. we have sparklers. will not pop and fizz but look impressive.

Sparklers and lighter fluid? What could possibly go wrong?

yeah, better not.
maybe dc has to paint lava or something...
