Stella ★★★★★

The invisible ink feature was a huge hit with my kids, and watching their faces as the messages appeared was priceless. We spent an entire afternoon making scented markers and experimenting with color mixing. Great activity that kept them engaged and learning.

Benjamin D. ★★★★★

My daughter loved mixing the colors to make her own markers, and the invisible ink activity kept her busy for hours. It's a fun, hands-on way to learn about color theory.

My six-year-old has been obsessed with making her own markers, and the invisible ink experiment kept her busy for an entire afternoon. The color-changing pens actually work, which surprised me.
