Safe makeshift alternative to solar eclipse glasses

The solar eclipse is coming and I am was not prepared!
All special solar eclipse glasses are sold out here and the Kindergarden was desperately looking for glasses for the kids to watch the eclipse.
This morning I had some time and with some household items, I built a camera obscura.
These items alsong with my trusty old tripod make a safe alternative to the special solar eclipse glasses.
The projected image is about 3mm in size, just sufficient to make out the disk of the sun. - And hopefully the missing bits during the eclipse.
That is what the projected image looks like with my digital camera's macro lens.

Looks promising to me.

Here are the instructions in detail:

Edit:
Worked great!
