Toilet bowl cleaner - homemade

It frothed and foamed over the top of the ice cube tray,

baking soda and citric acid, sal suds and hydrogen peroxide

mix gently, the recipe said, so it doesn't froth

so much for first time attempts at home made products

I laughed

with every attempt will come potential disaster

but without serious consequences, no lost lives,

no birth defects or hurt feelings, no harm done.

after a few hours, I broke off a few pieces and 

used as instructed, dropping some into the toilet

bowl and watching what was left of the froth.

I'm not sure how to improve my methodology

but it will be fun to find out.
