The following items are demonstrated in the video and described in the voice-over:

1. Assorted bump dots - Various kinds of stickers with protruding dots on them that can be put onto appliances to make them more tactile.

2. Pocket money brailler - A device that allows you to imprint braille onto paper notes, indicating their value.

3. Liquid level indicator - A device hung on the edge of a container with metal prongs that detect when liquid has reached it.

4. Braille Pop-It - A pop-it with the alphabet in braille on each bubble.

5. Tactile Rubik's cube - A rubik's cube with unique textures for each color.

6. Braille color clothing tags - Tags with braille to indicate what colour a piece of clothing is.

7. Signature guide - A card with a rectangular slit in it to guide the user when writing their signature.

8. Low vision playing cards - Cards with very large and colorful numbers on them.

9. Pop-A-Cell - A plastic card with 6 bubbles you can indent to practice braille characters.

10. Talking keychain clock - A clock that says the time aloud when you press a button.

Each lacewing spends about 5 days maturing inside its cacoon, and then it cuts an opening in the top and emerges as a fully-developed adult.

Green lacewing larvae (genus Chrysopidae) are also known as "aphid lions," because they're voracious predators that often feed on aphids. They've also been known to prey upon caterpillars, leafhoppers, planthoppers, thrips, spiders, mites, and insect eggs, which is why they're widely used to help eradicate pests in agricultural contexts.

Once the lacewing nears the end of its larval stage, it builds a small cacoon out of silk and then tucks itself inside, allowing the pupal phase to begin. Its tiny green body is often partially visible through the thin, loosely-woven walls of the cacoon.

These breathtaking photos of a lacewing climbing out of its cacoon were taken by a Danish photographer named Frederik Leck Fischer.

When the insect initially emerges, its wings and antennae are still compactly folded down against its body, and the wings have a dark, shriveled appearance that makes them almost unrecognizable.

The wings then gradually expand until they have reached their full size, which usually takes about an hour or two.

Fischer's photographs provide a stunning account of the entire process.
