window blocks

M has these great foam blocks that we use all the time (we're big fans of blocks).  Today we came up with a new use for them that M had a lot of fun with.  We used water to stick them to our slider and make pictures...

We got a small bowl of water to dip the blocks in and then we stuck them to the glass.  We made a tower and then some letters.  M's favorite part was the dipping...

but he also caught on to the sticking part.  He was also a fan of splashing which is why we only used about a cup and a half of water.  However, I put paper towel under the bowl and when doing this again I would definitely use a towel (or two).  If you have anything made of that foamy material it's a great activity because the pieces just wipe off at the end.
