Butterfly — fly!
The colors of nature are always inspirational to us. When natural plant pigments encounter chemistry, a remarkable color tour is therefore unfolded. In this year’s BASF Kids’ Lab, children learnt to use everyday materials rather than a brush to color their paper butterflies, creating a lot of unique and beautiful patterns while exploring t of the acid-base property of of materials.
Paint your walls to bring your home a new look, and apply spray coating on your car to make it look more dynamic. Everyone enjoys the refreshment of colors. If you have a playful spirit, follow Dr. Bubble to create your own colors!
Mallow flower is a purple flower native to Europe, which is known as the miracle of flower. It initially assumes a bright blue and then gradually turns purple as it reacts with oxygen in the air. After adding some lemon juice to it, the color will evolve to red purple and eventually to beautiful pink, like the glow of the dawn sky. It contains an amazing pigment called anthocyanin, whose color can change as the environmental pH changes.
For coloring — mallow tea, lemon juice, sodium soap, cotton swabs, white watercolor correction pen, paperboard with a butterfly pattern (attached with the publication)
Auxiliary materials — tape, colored iron wire, iron sheets, sponges, scissors
Step 1. Use a sponge dipped with mallow tea to color the butterfly on paperboard.
Step 2. Use a cotton swab dipped with lemon juice and sodium soap to paint the butterfly with beautiful patterns. Find the surprising effect with the correction pen.
Step 3. Use scissors to cut off the butterfly along the black line.
Step 4. Use adhesive tape to fix iron sheets inside the black circles at the back of butterfly wings.
Step 5. Add a butterfly body: fix the colored iron wires in the middle of the wings with adhesive tape.
Step 6. Slightly fold down the wings.
Step 7. Let the butterfly fly at your fingertips!
More about Anthocyanin
Anthocyanin changes color as the pH changes, and thus is a natural acid- base indicator: it assumes red when encountering acid, purple in neutral environment and blue or green when added with base. We can use mallow tea to test what else in our kitchen is acidic or alkaline.
Besides mallow flower, grapes, blueberries, strawberries, eggplant, purple cabbage, purple sweet potato, hydrangea and morning glory can also change color under the same principle.
Anthocyanin is a powerful antioxidant that protects human body from damage caused by free radicals or other hazardous substances. What’s more, anthocyanin is also able to enhance blood vessel flexibility, improve circulation and skin smoothness, inhibit inflammation and allergies, as well as improve joint flexibility.
Kipepeo <unk> kuruka! Rangi za asili sikuzote hutufundisha mambo mengi. Kwa hiyo, rangi za mimea zinapokutana na kemikali, rangi hizo hutokeza rangi mbalimbali. Katika maabara ya watoto ya mwaka huu ya BASF, watoto walijifunza kutumia vifaa vya kila siku badala ya brush rangi yao ya karatasi, kuunda mifumo mingi ya kipekee na nzuri wakati wa kuchunguza mali ya asidi-msingi ya vifaa. Paka rangi kwenye kuta ili kuifanya nyumba yako ionekane mpya, na tumia spray coating kwenye gari lako ili lionekane kuwa lenye nguvu zaidi. Kila mtu hufurahia rangi zenye kuburudisha. Ikiwa una roho ya kucheza, fuata Dakt. Bubble kuunda rangi yako mwenyewe! Maua ya Malva ni aina ya maua ya rangi ya zambarau ambayo hutoka Ulaya na ni maarufu kama'muujiza wa maua'. Mwanzoni huwa na rangi ya bluu yenye kung'aa na kisha hatua kwa hatua huwa na rangi ya zambarau anapokabiliana na oksijeni iliyo hewani. Baada ya kuongeza maji ya limao, rangi yake inakuwa nyekundu na hatimaye rangi ya waridi, kama mwangaza wa jua. Ina rangi ya anthocyanin, ambayo inaweza kubadilika kulingana na pH ya mazingira. Kwa rangi <unk> malow chai, maji ya limao, sabuni ya sodiamu, swabs pamba, nyeupe watercolor marekebisho kalamu, karatasi na butterfly muundo (kuambatanishwa na uchapishaji) vifaa vya kusaidia <unk> mkanda, rangi ya waya wa chuma, karatasi ya chuma, sifongo, scissors Hatua ya 1. Tumia sifongo iliyotiwa chai ya mallow kupaka rangi kipepeo kwenye karatasi. Hatua ya Pili Tumia swab ya pamba iliyotiwa maji ya limao na sabuni ya sodiamu kupaka kipepeo rangi yenye michoro maridadi. Tafuta athari ya kushangaza na kalamu ya kurekebisha. Hatua ya 3. Tumia mkasi kukata kipepeo kando ya mstari mweusi. Hatua ya nne. Tumia mkanda wa kunata ili kurekebisha karatasi za chuma ndani ya duara nyeusi zilizo nyuma ya mabawa ya kipepeo. Hatua ya Tano Kuongeza mwili kipepeo: fasta rangi waya chuma katikati ya mabawa na mkanda wa kunata. Hatua ya 6. Funga mabawa kidogo chini. Hatua ya 7 Acha kipepeo aruke kwenye vidole vyako! Anthocyanin ni rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi ya rangi. Kwa mfano, unaweza kutumia chai ya malwa kugundua ikiwa chakula chako ni cha asidi au cha alkali. Mbali na maua ya malow, zabibu, blueberries, strawberries, eggplant, kabichi ya zambarau, viazi vya rangi ya zambarau, hydrangea na utukufu wa asubuhi pia inaweza kubadilisha rangi chini ya kanuni hiyo hiyo. Anthocyanin ni antioxidant yenye nguvu ambayo inalinda mwili wa binadamu kutokana na uharibifu unaosababishwa na free radicals au vitu vingine hatari. Zaidi ya hayo, anthocyanin pia ina uwezo wa kuongeza kubadilika kwa mishipa ya damu, kuboresha mzunguko wa damu na usafi wa ngozi, kuzuia uvimbe na mzio, na pia kuboresha kubadilika kwa viungo.
