Wasp nest

Often seen as pests, wasps have an important role in pollination (especially figs) and can be used for biocontrol. Social wasps make their paper-like nests out of broken down pieces of wood and other material. Here I have the images of a nest with plane and cross-polarized light.

Croton plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to Codiaeum variegatum. The generic name comes from the Greek κρότος (krótos), which means “tick” and refers to the shape of the seeds of certain…

Pollen grains: tactoids and spiky spheres

Hi Foldscope Expolorers! This is my first foldscope adventure. Last year, Manu shared the joy of foldscopy with a bunch of us at the University of Chicago. Yesterday, I finally built my own foldscope and I’m excited to try it out! Next week, I will share foldscopy with some Chicago Public School teachers. Hopefully, their…

Magnesium Sulphate – Polarizing movie

For a few pennies, I was able to get some Epsom salts. I added water and let it dry on the slide and then viewed with polarizing filters. Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early….

Magnesium Sulphate (Epsom Salt) crystals.

Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early. It is also called Epsom salts and used for soaking and skin healing.

Serendipitous Dance of Polarizing Crystals – MgSO4

For a few pennies, I was able to get some Magnesium sulphate. I mixed in water and allowed it to dry on the slide. I thought it had dried, but when I looked at the clip I realized there was a drop of water (at about 7 seconds into the clip) at the top of…

Monosodium glutamate crystals

Monosodium glutamate (MSG) is responsible for the umami or “savoury” taste of many of our foods. I was able to buy a tiny amount at a bulk food store for only a few pennies….can’t recall the last time I bought something so interesting for only a few pennies!

Raw Honey – polarizing light clip

Raw Honey often contains pollen and tiny bits of beeswax. I think the structure at about 4 o’clock maybe wax, but am not sure if I can say so confidently. As you watch the clip under polarized light, you can see the sugar (primarily glucose and fructose) crystals shimmering. Ambient room temperature is quite high…

Methotrexate – short movie clip with polarizers

Here is a short clip of the Methotrexate crystals under polarizing filters.  Methotrexate was one of the first chemotherapeutic agents (and still used), and was discovered by Yellapragada Subbarao, who also had major contributions in elucidating the role of ATP and earliest antibiotics.

More Potash

Here is a short polarized film of potash which contains a number of potassium compounds. You can see the birefringent potassium nitrate crystals.


Here is Potash with polarized light and you can see the birefringent KNO3.

Egg White

Chicken egg is the best source of protein, lipids, vitamins, and minerals. Eggs consist of 3 main components: eggshell, egg white, and yolk. Albumen commonly known as egg white is rich in proteins. Albumen color is opalescent and doesn’t appear white until an egg is whipped or cooked. Egg whites are a low-calorie food containing…
