š± Composteren kun je leren! Met een wormenbak in je tuin, dak- of balkontuintje doe je dat namelijk gewoon lekker zelf. Op 8 februari maak je met slimme tips & tricks je eigen wormenhotel en word je hotelmanager van de kleinste hotelketen van Rotterdam!
š HOTELMANAGER? Ja, echt. Naast dat je je eigen wormenhotel maakt, word je ook opgeleid tot rasechte manager.
Wat heb je nodig?
Voor dit wormenhotel heb je weinig nodig. Mayobakken, of andere horecabakken van 5 liter die goed op elkaar passen, een boormachine met een 2mm en 6mm boor, een stanleymes
Today’s guest post is brought to you by Amida who writes at the wonderful blog, Journey Into Unschooling. Here she shows you a great way to re-use plastic soda bottles or juice cartons to create an upside-down tomato planter!
I’ve always been fascinated with growing tomatoes upside-down, but, $19.99 (which was what my local garden supply store was selling it for) seemed a bit steep to pay for what essentially is a bag you fill with dirt! So I decided to make our own using some very basic materials we had around the house.
Here’s what you’ll need:
* 2-liter bottle or juice carton
* Garbage bag
* Duct tape
* Tomato plant
* Utility knife
* Paper towel
* Cotton balls
* Twine
Step 1.
Using the knife, carefully cut off the bottom of your bottle or carton.
Step 2.
Roll up a garbage bag around your arm andĀ insert into the bottle. Once inside, loosen the bag
and try to spread it evenly within the bottle. TheĀ reason I used the black bag was to keep the roots covered and hopefully warm in the sun.
Step 3.
Fold the top edge of the bag over theĀ bottle and secure with duct tape.
Step 4.
Wrap a tomato plant with paper towel andĀ carefully insert into the bottle and out through theĀ spout. The towel will help keep the soil together.
Step 5.
Fill the rest of the bottle with soil.
Step 6.
Wrap some twine or string at the mouth of
the bottle, stretching along the length of
the body, and tape in place.
Step 7.
Stuff some cotton balls through the bottom opening to help keep water in.
Step 8.
Hang in a sunny spot and water thoroughly.Ā Our plants have been growing strong for at least
three weeks now and appear to be doing well. WithinĀ the first week, the plant flipped around and started
growing upwards.
Another advantage I’ve noticed is that there that are no bugs on the plants! Perhaps in thisway, they will survive a little longer than our usual crop and maybe even provide us with some juicy tomatoes this summer.
DNA. Itās what encodes the genetic material of every living thing. And it also makes a yummy cocktail.
This video, which stars TED Fellow synthetic biologist Oliver Medvedik, shows you how to make a delicious adult beverage out of frozen strawberries, pineapple juice and Bacardi 151. Follow the adorably animated instructions, and youāll be able to isolate the DNA of strawberries while making a shot. Throughout it all, Medvedik ā who co-founded New York Cityās community biolab GenSpace (see photos of their incredible office building) ā shares the science of why he chose strawberries for this recipe and reveals exactly what each step does toward isolating DNA.
Some of you may be wondering: can you make a non-alcoholic version? Yes, says Medevik, but it would require using a substance like chloroform or phenol. Medevik explains, āIt would have to be an organic solvent where the DNA is poorly soluble. Alcohols, such as isopropyl or ethanol, are good since they are fairly nontoxic, cheap and have the right chemical attributes.ā Look, but donāt drink.
This video was shot by cinematographer Peter Olsen, directed and edited by TEDās own Kari Mullholland, sound designed by Arjun G Sheth and animated by Joy Buran, James Buran and Noelle Melody of Twins Are Weird. It was shot at GenSpace, where everyday citizens can learn about biotechnology.
Enjoy the video. And cheers! To tinkering with the stuff of life.
