Ice Cube Trays Make Better Sandcastles Than You Do
It's 3 p.m., and all you have is a bag of sand and an empty ice cube tray. That's enough. The kids build the castle, and you lose the building contest.
How it went: We used sand. We had rocks and other small toys: balls, square cubes, some ice cube trays and some scoops. We played with it kind of like a sandcastle.

Why bother
Damp sand packs. Dry sand won't. Kids work out the difference with their hands. An ice cube tray's a brick mold. A rock's a tower top.
You don't have to make it a castle. Filling and dumping is plenty.
The castle will fall over. That's the part they'll ask to do again.
What you'll need
- About 40 lb of sand labeled play sand, not construction or all-purpose sand. We vetted this natural, uncrushed play sand* (affiliate link).
- A wide, shallow bin
- Smooth rocks, balls and cubes, each too big to fit through a toilet-paper tube
- One or two ice cube trays
- Scoops and a castle mold, like this sand play set* (affiliate link) (labeled 18 months+)
- A spray bottle of water
- An old sheet under the bin

Quick start
- Spread the sheet and set the bin on it.
- Pour in sand about 2 inches deep. Pour low and slow.
- Mist one corner until a squeezed handful holds its shape.
- Put out the rocks, balls, cubes, trays and scoops. Say nothing.
- Pack a tray with damp sand, flip it, lift. Now you have bricks.
- Build until someone knocks it down. Then it's over, or it's round two.

Discover moment: Fill a tray with dry sand and flip it. Then try damp sand. Ask, "Why did this one stay up?"
Connect moment: Build your own tower next to theirs. Yours will be shorter. You'll be told how to fix it.
Too much? / Too easy?
Too much (2): Dry sand, two big scoops and three big balls. Fill and dump.
Too easy (3-5): Sort it. Rocks in one tray, cubes in another, balls in a scoop.
Too easy (6-8): Build a castle with a moat and a ball run down one side. Time how long it stands.
Cleanup
Brush sand off hands and clothes over the bin. Wet sand can grow bacteria, so don't put the lid on until it's dry. Shake the sheet outside. Rinse the toys.
What I tell friends: Sand, a few rocks and an ice cube tray make a castle. That's the whole pitch.
Supervision: Sit within arm's reach of anyone under 3 the whole time.
Small parts: For under-3s, every rock, ball and cube must be too big to fit through a toilet-paper tube. Balls need to be wider than 1.75 inches. Keep marbles, pebbles and coins out of the bin.
Sand: Buy bags labeled play sand. Skip construction sand, crushed quartz, limestone or marble, and anything that looks dusty. Breathing crystalline silica dust can cause serious lung disease.
Eyes: No throwing sand. If sand gets in an eye, don't rub it. Let tears work, then rinse with clean water. See a doctor if it still feels like something's there.
Mouths: Sand and rocks aren't food. Snacks don't go near the bin.
Water: A spray bottle is enough. Empty any bucket of water right after use.
Hygiene: Wash hands after play. Cover the bin between uses so pets and bugs can't get in.
