This idea for Invisible Letters was an accident…I was trying to make some sight word stamps (by writing sight words backwards on large lids with a hot glue gun), but that was a complete and total fail. They didn’t work as stamps because the hot glue wasn’t a completely smooth surface, so the ink stuck to some of the hot glue but not other parts. The stamped image was, in turn, unreadable. Here is a glimpse at my attempt…
Once I realized this idea had failed, I started to peel the glue off the lids (so I could reuse them for something else, of course). It was then that I recognized that the dried hot glue letters were actually pretty cool all by themselves! :)
Here’s what you’ll need: a hot glue gun and a smooth, heat-proof surface.
1. Use your glue gun to carefully write every letter in the alphabet (capital and lowercase, if you’re really ambitious…we just did capital letters). I used a plastic lid from one of my cake pans as the surface. In hindsight, they were less “invisible” since I used this lid because it had a design that then was transferred onto the bottom of the letters.
2. Let them dry completely. Then use a butter knife to pry the edges off of your flat surface.
Now you see them…
…now you don’t (well, you kind of do…but you get the point). :)
Once you’ve made them, store them in a plastic bag for next time!
There are so many ways you could use these flexible letters…alphabet ordering, crayon rubbings, hidden in a sensory tub, and in letter boxes (just to name a few).
