You don’t need much preparation for this activity for days when you don’t have much time. You just need to forgo a few metallic gel pens to amaze your kids.
What you’ll need
- Metallic Glitter Gel Ball Pen
How to Set Up
- Disassemble the gel pen. Remove the outer tube, the nib, and else. We only want the inner tube with gel ink.
This experiment shows that objects or liquids have different densities. The less dense object will float, so the gel ink is less dense than water. The glitter sinks as it is heavier than water.
