What Is Small But Heavy

What is small but difficult? 3

I have to weigh my solar oven. Only respond with used or available items.

Stones or objects that you place on paper so that the paper does not fly away.

In general, you should not worry about the weight of the fish, although lead people are not currently available because they are well aware of the poison.

Otherwise, br and other heavy metals ... the moment I read your glasses, I took pictures (how builders use them), will probably work.

Forgive your ignorance, but if your solar oven is outside you can fill a plastic bottle with sand but I don't know what you mean by small things ...

Specific types of calculators. You can take a relatively small glass and fill it with liquid or solid. The stapler is a little heavy. Too many batteries stuck. Stackable CD case.

Try some stones. They are usually heavier than bricks.
