Answer 1

Try this out

Cut the top of the bottle (use a knife but be very careful)

Fip the botlle top up side down

Put some peices of cloth, or cotton, or something let water out but not the sand. Make sure you cover the whole bottle top

Fill sand in, pack it tight

Pour water in

It may fail if you can't hold the sand. (depend on the sand 's quality, you will have good/bad water)
