Take a drop of ammonium hydroxide,
Stir well into a beaker of cyanide,
Carefully pour in some con. nitric acid,
Then making sure your expression is placid,
Add a tincture of lead hyperchlorate,
Followed closely by sodium zincate;
Next mix in some potassium sulphite,
Then smiling sweetly advance and ignite ...
The mixture will get frothy and bubble,
But do not worry you aren't in trouble,
Just plug into the nearest anode,
Hold it close to your face and - explode
Don't worry about the mess und the muck,
It won't be you that will have to clear up!!
G. O'Hagan, 5A
