I wanted a volcano that would do several things...
erupt with lava
and finally, make volcano noises.
Please check out my other instructables and I also have a diy podcast called mechanicalmashup.tv
Step 1: Lava
The actual lava was made by blending a $10.00 bulk bag of frozen strawberries with some icing sugar and corn starch. This was reduced on the stove to thicken. The flow rate was tested and the sauce was frozen. This was a mistake because I think freezing the sauce changed it's consistency slightly and it did not flow as well as I would have liked on the big day.
Step 2: Making the pan
Step 3: The box
I used a flapper disk on my grinder to round the edges and it worked really well.
I painted the box with a textured spray paint that looks like rock.
I welded the handles up and mounted them a little off centre to compensate for the weight of the fountain inside.
