Exploring Magnets with Preschoolers

This simple magnetic Valentine discovery bottle is a fun way for preschoolers to explore magnets safely. This activity is designed for kids age 3 and up, who will not try to put any magnets in their mouth. Swallowing magnets can be extremely dangerous.

What you’ll need to make the magnetic Valentine discovery bottle:

  • Meodynium coin magnets (be VERY careful not to give these to kids unsupervised!)
  • Clothespin
  • Hot glue gun and glue sticks
  • Felt hearts
  • Red glitter
  • Clear school glue
  • Clear bottle (we used Smart Water)
  • Heart confetti

Make your magnet wand by stacking 3 or 4 coin magnets together. Glue the magnets to the end of the clothespin with hot glue. Do not let your child play with the magnets without supervision, because although the magnetic grip is strong, it is possible to remove the magnets and swallow them. Only do this project with a child who won’t try to eat the magnets.

Glue a few magnets to the back of some of the hearts.

Pour 1/4 of a cup of glitter and the glue into the water bottle after removing the label (oil helps it come off quick). Fill the bottle with warm water and shake to mix.  Add in a few confetti hearts.

Put the magnetic hearts and some of the regular felt hearts into the bottle.

Seal the lid tightly.

Give the bottle to your preschooler to play with. Show your preschooler how the magnetic wand will pick up the magnetic hearts, but it won’t be able to pick up the felt hearts.
