Viscosity

In 6th grade, I did a project measuring viscosity. I got 5 of the same tall containers with lids, and I filled each one with a different liquid. I used water, italian dressing, honey, olive oil, and grease. I then put the same sized marble in each, and I timed how long it took for the marble to get from the top of the container, to the bottom, and did several trials. I ended up getting 2nd place. :( I feel like I should have got 1st, but another kid brought in 3 giant fishtanks, so how could he not win. lol. Good luck ya'll!

Glow in the Dark

I was in fifth grade, and I did a glow in the dark project. I made a glow in the dark penny, wrote the title in glow in the dark letters, etc. I put on mini curtains, so that the person looking at it it could put the curtains over their head, and it would be dark. Oh, I also did tonic water (that glows in the dark, too) and that type of thing.
