Question

Can the cardboard be larger?

Community Answer

Size actually helps stabilizing it. But, more size might not go with the look and, also, if it gets any bigger it may not be visible from certain top angles.

Question

There are only four dowels used in it, so why do I want the twelve dowels?

Community Answer

If you are using skewers to make dowels, you will need three skewers to make one dowel. 3 x 4 = 12.

Question

Can we do it with a small bottle also?

Community Answer

Yes you can but you will have to adjust the measurements. Depending on the size of the bottle you will likely have to halve the amount of sand you put in.

Question

Can I make a sand timer from a large bottle?

Community Answer

Yes, it doesn't matter how big the bottles are, you just need two of the same size. It will realistically run longer if the ratio of the sand and bottles remains the same.

Question

What will happen if the sand isn't dry?

WikiBoat

Community Answer

It will clump together and might clog up the timer. Make sure to dry sand throughly and without large clumps before use.
