Grades 5 and Up. High-quality bowl provides a hands-on demonstration of the behavior of waves and frequencies.

  • Just rub the copper handles, and the vibrations make the water surface ripple
  • Soon, water droplets shoot up, quickly becoming continuous fountain streams
  • Silicone material and honeycomb design of mat stop bowl from slipping and prevent vibrations from transferring to table, allowing waves to build higher
  • The 7 in. mat can withstand temperatures up to 480° F (250° C)
  • Also includes teacher’s guide
