Fun Facts about Bubbles

  • When many bubbles join together it’s called foam.
  • On May 16, 1999, 23,680 gathered at a soccer field in London for a mass bubble-blowing event.
  • Children have been blowing bubbles for at least 400 years.
  • It’s possible to freeze bubbles.

Instructions

  • Poke a hole with a pencil in your paper cup, about 1 inch from the bottom.
  • Stick the straw through the hole and push forward, but don’t let it touch the other side. Have the bendy portion on the outside of the cup, facing up.
  • Use masking or duct tape to secure the straw on the outside. Make sure you’ve plugged any cracks so the straw doesn’t leak.
  • Pour  dish soap into the cup, enough to cover the straw. Make sure the bendy part of the straw is pointing up or the soap will pour out.
  • Add 2 tablespoons of water.
  • Add a few drops of food coloring if you’d like colored bubbles.
  • Gently blow through the straw and watch the bubble overflow (this is best done outside).
  • You may choose to decorate your bubble machine with markers, stickers, etc.
