Great fun, but patience required

The expansion process is fascinating for children, though it takes about 20-30 minutes for full growth. The colors are vibrant, and the figures are detailed enough for small hands to hold.

Mess-free magic

Unlike bath bombs that leave residue, these just sit in the water and grow. Cleanup is easy, and the kids can play with the expanded figures after the bath too.

Perfect educational toy

As a preschool teacher, I used these during our ocean unit. The children were mesmerized. They shrink back down when dried, which is a great lesson on absorption and evaporation.

Good value for money

You get a nice variety of animals in the pack. Some expanded faster than others, but overall, it was a hit with my twins. Just make sure to supervise younger kids.

Safe and durable

I was worried about small parts, but these expand into solid, soft sponges that don't break apart easily. No strange smells either, which is a huge plus for bath toys.

Bathtime just got exciting!

My kids absolutely love watching these little capsules grow into dinosaurs and fish. It makes bath time so much more engaging, and I feel good knowing they are learning about different creatures while playing.

5 FAQ

Q: Can these toys be swallowed by accident?

A: While made from non-toxic materials, these are not edible. Please supervise children under 3 years old to prevent choking hazards before the capsules fully expand.

Q: How long does it take for the capsules to fully expand?

A: Typically, you will see significant growth within 15 minutes, with full expansion occurring between 20 to 40 minutes depending on water temperature.

Q: Can I put these in the dishwasher to clean them?

A: We recommend rinsing them with clean water and air drying. High heat in a dishwasher may damage the sponge structure over time.

Q: Are the dyes used safe for sensitive skin?

A: Absolutely. We use skin-safe, non-staining dyes that meet all international safety standards for children's bath products.

Q: Do the figures shrink back to their original size?

A: Yes! Once removed from the water and allowed to dry completely, the sponge material shrinks back down, allowing you to reuse them many times.
