The sand floats upwards - about $18.90 a timer

Six timers, 8.5 x 3 x 13.5cm each, in which the sand rises instead of falling. Run time varies between 2 and 3 minutes depending on temperature.

These are a teaching resource, not a toy. The supplier is explicit and so are we: they must be used with care, they may break if dropped from a height or used with force, they need adult supervision, and they must not be accessible to children without it. Each is filled with mineral oil. Recommended for children aged 3 years and older.

With that said, the reason to buy them is that they break an assumption. Every child knows sand falls. Watching it rise is the moment a five-year-old starts asking why - and that question is worth more than any worksheet on density.

The variable run time is a feature rather than a fault. Warmer oil runs faster, so the same timer is quicker in a sunny room than a cold one, which is a second experiment sitting inside the first.

FAQs

With adult supervision, for ages 3 and up. The supplier states plainly that they are not a toy, that they may break if dropped from a height or used with force, and that they must not be accessible to children without supervision. Each is filled with mineral oil. Treat them the way you would treat glassware in a science lesson.
Temperature. The oil runs faster when it is warm, so the same timer takes closer to 2 minutes in a warm room and closer to 3 in a cold one. Do not use these where an exact duration matters - use the visual timer for that.
The grains are less dense than the oil around them, so they rise instead of falling. That is the whole lesson, and it is a better one than most because the child sees something that contradicts what they expected.
Six is a small group with one each, or a discovery table. At about $18.90 a timer they are not a consumable - keep them together and count them back in.
Stop, keep children away, and clean it up as an adult - there is mineral oil inside. Then bin it. This is the reason the supervision requirement is not optional.
