This blood model sensory bottle lets kids see what’s floating around inside their bodies, with squishy red beads, “white blood cells” and glittery “plasma.” It’s the perfect mix of “eww!” and “wow!”
It takes about five minutes to make, and somehow turns into half an hour of everyone arguing over who gets to shake it next. Great for a human body unit, a science center or a rainy day.

Add the red water beads
Drop the red water beads into the bottle. These are the red blood cells, so use lots. At least one will roll away forever.
Add the beans
Add just a few plastic navy beans for white blood cells. Real blood has far fewer white cells than red ones, so a handful is plenty.
Add the glitter
Sprinkle in some gold glitter for platelets. A pinch or a handful, depending on how sparkly you like your science.
Add water and corn syrup
Pour in water, then drizzle in corn syrup. The golden mix stands in for plasma and gives everything that slow, hypnotic drift.
Glue the lid and shake
Run a line of super glue around the rim and screw the lid on tight. Let it dry, then shake, roll and tilt it and watch everything tumble.
⚠️ Water bead safety
Water beads are dangerous if swallowed, so never let kids play with loose ones. Glue the lid shut, check the bottle for cracks, and keep it for supervised play.
The Science Behind the Blood Model
Each part of the bottle stands for something in real blood:
- Red water beads = red blood cells. They carry oxygen all over the body.
- Navy beans = white blood cells. They fight germs and help keep you healthy.
- Gold glitter = platelets. They rush in to help stop bleeding when you get a cut.
- Golden water and corn syrup = plasma. This yellowish liquid carries everything else around the body.
Fun fact: plasma makes up about half of your blood, and red blood cells make up most of the rest. White blood cells and platelets are just a tiny part.

Blood Model Sensory Bottle FAQ
Fill a clear bottle with red water beads, a few plastic beans and gold glitter, then add water and corn syrup. Glue the lid on tight.
Red beads are red blood cells, beans are white blood cells, glitter is platelets and the golden liquid is plasma.
Yes. Red pony beads or red pom poms work and are safer if you have little ones around.
Only if the lid is glued shut and an adult is close by. Loose water beads are dangerous if swallowed.
